Best and Worst Deals at Costco To Watch Out For

If you’re a savvy shopper, your Costo membership can oftentimes pay for itself with all the savings you can rack up. However, not every item sold by the members-only warehouse club is a bargain.

For some things, Costco warehouse deals might be the best in town. Others, however, won’t actually save you money. So you can shop smarter, find out what you need to skip and what you should buy at Costco.

25 Best Costco Deals

Between its discount kitchenware, alcohol and diapers, stocking up at Costco can save you big time. Here’s what to look for at the warehouse store.

1. Snacks

Costco is a good place to stock up on the snacks that you know your household will go through quickly.

“One thing I only buy at Costco is Pepperidge Farm Goldfish,” said Mike Collins from DadSense.co. “My kids love them and they make a perfect snack for school lunches. My local supermarket sells a 30-ounce box for $8.99. But Costco sells a 58-ounce box for the exact same price. That’s double the snacks for the same price!”

2. Rotisserie Chicken

You’d be hard-pressed to find better prices for rotisserie chickens, according to Collin Morgan, owner of Hip2Save.com.

“One of our favorite Costco deals is the classic rotisserie chicken,” she said. “Costco sells bigger chickens than most grocery stores for $2 to $3 less. These are a great bargain as-is for meals, but we like to buy them for recipes that call for shredded chicken.”

3. Diapers

Morgan recommends Costco’s store-brand diapers to get the best bang for your buck.

“Some Kirkland items are made by bigger name brands; Kirkland diapers are rumored to be made by the manufacturer of Huggies,” she said.

4. Batteries

Batteries are another Kirkland Signature item that’s worth buying.

“Kirkland batteries are actually made by Duracell, but the prices are much less than the name brands,” Morgan said.

5. Organic Maple Syrup

You don’t have to pay an arm and a leg to eat organic, especially if you look for deals on organic foods at Costco.

“Costco has cheap — and delicious — organic maple syrup for only 39 cents an ounce, a bargain compared to Walmart or Amazon, which sell it for 69 cents an ounce and 80 cents an ounce respectively,” said Katie Holmes of OutwitTrade.

6. Gift Cards

“You’ll almost always see a discounted rate for gift cards at Costco,” said consumer analyst Julie Ramhold with DealNews.com. “It might not be a huge amount, but it’s common to see things like two $25 See’s gift cards for $39, or four $50 Texas de Brazil gift cards for only $150. Considering all you have to do is be a member, that’s a hard discount to beat.”

In addition to discounted restaurant gift cards, you can find theme and water park tickets, movie tickets, gym and weight management gift cards, and experience gift cards at discounted rates, she said.

“You can also find $100 Apple App Store gift cards for around $90,” Ramhold added.

7. Prescription Medication

Costco often has cheaper medication than chain pharmacies, especially for generics, Ramhold said.

“For instance, a 30-day supply of generic Zoloft can be as much as $12 at pharmacies like CVS,” she said. “At Costco, a 90-day supply is closer to $8. That’s roughly 8 cents per pill at Costco versus 40 cents per pill at CVS.”

8. Alcohol

Not all Costco stores sell alcohol, but you can find great liquor deals at the ones that do, Ramhold said.

“For instance, many shoppers swear by Kirkland French Vodka — in fact, rumors abound that it’s actually Grey Goose, although that’s been disproven,” she said. “However, the reason people are so ready to believe it is because the vodka is just that good. Your mileage may vary on how much you’ll save, but Costco’s vodka is usually around $20 for 1.75 liters, and my local liquor store charges $60 for the same amount of Grey Goose.”

9. Flowers

You can justify buying flowers “just because” when you buy them at Costco.

“Costco makes every month feel like Valentine’s Day with their deals on flowers,” said Rebecca Gramuglia, retail expert at TopCashback.com. “Skip the $30 to $50 flower arrangement and head over to Costco for big bunches for under $15.”

10. Baby & Kids' Clothes

“You can always find great deals on baby/toddler clothing and sleeper sets at Costco,” Gramuglia said. “Whether you shop online or head to the store, Costco carries Carters, Nautica, Calvin Klein and many more.”

11. Kitchen Furniture

Howard Schaffer, general manager of Offers.com, recommended visiting Costco Wholesale for a wide range of kitchen items.

“You can score tables, chairs and tablecloths at Costco in a variety of sizes for a great price,” he said. “Costco even offers kids tables and buffet tables if you’re looking for something different.”

12. Kitchenware

For large crowds and potluck-style dinners, Schaffer noted the importance of having chafing dishes to keep food warm — and advised purchasing them at Costco. It’s also a great place to purchase glasses and dinnerware for hosting or everyday use.

“Costco sells disposable plates, napkins, cups — including wine glasses — and silverware in bulk for cheap,” he said. “You can also stock up on other glassware or [serving ware] if disposable settings aren’t your forte.”

13. Wrapping Paper

For quality wrapping paper, steer clear of the dollar store.

“Costco sells four-packs of heavy-duty wrapping paper for $11.99 or about $3 per roll,” said Kendal Perez, a former savings expert with CouponSherpa. “Although you can buy wrapping paper from dollar stores for just $1, these rolls only contain about 17.5 square feet of paper, compared to Costco’s 45 square feet per roll, making the cost per square foot comparable.”

14. Gourmet Treat Baskets and Tins

Perfectly packaged Costco gifts are great for any occasion.

“You can find large gourmet gift baskets and treat tins for great prices at Costco,” Perez said.

15. Pumpkin Pie

Costco has been selling its famous pumpkin pie for $5.99 since 1987. The only way the pie has evolved is growing from 10 inches to its current size of 12 inches, according to a recent article in the Costco Connection.

“It’s delicious and feeds a lot of guests,” Perez said.

16. Photo Printing

Costco 4-by-6-inch prints start at 19 cents each, and poster prints start at $6.99 each. In comparison, 4-by-6-inch prints start at 23 cents each at Walgreens and CVS, and poster prints start at $10.99 each. This might not seem like huge savings, but if you need a large volume of prints, the price difference can add up fast.

17. Kirkland Signature Bacon

Kirkland Signature bacon received a nearly 4 out of 5-star rating on the Consumer Affairs review site.

18. Eggs

Costco has both a great variety of eggs and great prices compared to many grocery stores, Business Insider reported.

19. Food Court Items

Costco is famous for its food court hot dogs and $1 churros — and the deals are so good that the warehouse store is now making them available only to members in certain locations, Fox News reported.

20. Olive Oil

Costco’s Kirkland Signature Organic Extra Virgin Olive Oil is professional-chef-approved. In the cookbook “Salt Fat Acid Heat,” Samin Nosrat recommends this brand as one of the best-tasting olive oils you can get for your money, HuffPost reported.

21. Almond Butter

Costco’s store brand of creamy almond butter costs $8 for 27 ounces — which is less than 30 cents an ounce. Not only is Costco’s almond butter cheaper than what you’d get at most stores, but it’s healthier too, Cooking Light reported. The only ingredient in Costco’s almond butter is roasted almonds, with no additional oils added.

22. Parmesan Cheese

Parmesan cheese has a longer shelf life than most other cheeses, so you can likely get away with buying it in bulk. Its per-unit cost is cheap compared to what you would get anywhere else, Business Insider reported.

23. Cereal

Cereal has a long shelf-life, so you can enjoy the great deals Costco offers on both name-brand and Kirkland Signature cereals without having to worry about it going bad.

24. Frozen Fruit

Smoothie lovers should stock up on frozen fruit during their next Costco outing.

25. Pure Vanilla Extract

If you bake a lot, you know that nearly every recipe calls for vanilla extract. Today recommends buying it at Costco — you can get a 16-ounce bottle for $25, while a 4-ounce bottle will cost you $12 at Trader Joe’s.

25 Worst Costco Deals

Although best known for its supersized deals, Costco has a few items you’ll want to consider skipping. You might find a better deal elsewhere.

ARTYOORAN / Shutterstock.com

1. Produce

Not everything is a good deal when bought in bulk, and produce is a case in point.

“It’s not that it isn’t quality produce — it can be really great — but unless you’re going to be able to eat it all fairly soon, you run the risk of it going bad,” Ramhold said. “Unless you have concrete plans for those 5.5 pounds of pink lady apples, maybe skip the bulk buy and opt for your local grocery store instead to buy only what you need.”

2. Books

If you go to Costco searching for a specific book, you might not find it.

“Costco stores can have an OK selection, but you’ll be able to find exactly what you want at Amazon,” Ramhold said. “Even better, opt to support a local indie bookstore — you tend to receive better customer service and you’re supporting local, so it’s a win-win.”

3. Spices

“Costco has a variety of dried spices, but unless you use them frequently, you’re probably better off buying smaller quantities elsewhere,” Ramhold said. “Spices won’t necessarily go ‘bad,’ but they will lose their potency over time. That huge thing of garlic powder might seem like a great purchase, but if it’s hanging around a year later, odds are it won’t taste nearly as good.”

4. Canned Goods

Canned goods are one item where the brand name really doesn’t matter, so you won’t necessarily get a better deal at Costco.

“Because Costco sells brand-name items, it’s cheaper to buy canned goods at your local supermarket. Pay less by purchasing generic options rather than name-brand products,” Gramuglia said. “More often than not, the difference is just the price tag, and generic products are just as tasty or reliable as notable, name brands.”

5. Laundry Detergent

“Before you’re tempted to buy a year supply of detergent from Costco, be warned that it typically loses some its effectiveness after six months,” Gramuglia said. “Instead, get a normal-sized container of your favorite detergent at Walmart for a great price.”

6. Frozen Turkeys

Frozen turkeys are typically better priced at grocery stores compared to Costco, Perez said. “I purchased a 14-pound Kroger brand turkey from King Soopers for 69 cents per pound, compared to Costco’s price of 99 cents per pound for Butterball frozen turkeys.”

Prices vary by store and the part of the country you live in, so check with all the local grocers in your area to find the best deal.

7. DVDs and Blu-Ray Discs

Costco Wholesale often places DVDs and Blu-ray discs near the checkout lines in an attempt to lure customers into making impulse buys while waiting in line to pay. But these items aren’t typically great bargains.

“You can find lower prices online or for pennies at your local thrift store,” said Stephanie Nelson, The Coupon Mom, who has conducted extensive research on wholesale clubs.

8. Condiments

Costco Wholesale offers condiments in bulk sizes, but bigger isn’t always better. After all, if you’re not getting through your tub of mayonnaise before it expires, you’re losing money.

“Unless you are entertaining, pay a lower cost overall by buying sale-priced condiments at the supermarket, with coupons that are frequently available on these items,” Nelson said.

9. Designer Clothing

As you are perusing the Costco warehouse aisles, it’s always exciting to stumble upon a display of designer duds, but this is one of those Costco sales that’s too good to be true. You might recognize the famous label, but chances are, the item doesn’t meet the same quality standards you’d find in the designer’s boutique or at an authorized retailer.

Sometimes the clothing is made from leftover fabric or it hails from an order that didn’t turn out as planned, according to a December 2016 article from digital media company Refinery29. As a way to earn extra money, the brand sells the subpar items to stores like Costco. You’ll get to sport the designer deal for a bit, but the quality won’t be what you bargained for.

10. Paper Products

Every good party host knows the importance of having enough napkins to go around, but Costco deals on these items aren’t always the best in town. Nelson said you can pick up sale-priced paper towels, toilet paper, napkins and tissues for less at supermarkets or big-box stores like Walmart and Target — and that’s before coupons.

11. Milk

Unless you have a large family who loves milk, chances are this purchase will go bad before you have a chance to finish it.

12. Off-Brand Appliances

With appliances, you often get what you pay for. For example, Costco sells a stainless steel five-burner grill for under $900 — which is less than what you’d pay for a Weber grill of the same size — but it doesn’t work as well as a higher-quality grill would, according to some reviews.

“The grill doesn’t get hot enough,” wrote one reviewer on the Costco website. “Maybe there’s something I’m doing wrong, but the only way I can get it somewhat hot is to keep all five burners lit and the lid closed…even then, it’s not hot enough to produce any grill marks.”

13. Flour

Flour has a limited shelf life so it’s not something you should buy in bulk, according to Eat This, Not That!

Arne Beruldsen / Shutterstock.com

14. Disposable Razors

You might be able to find better disposable razor deals elsewhere, even if you opt for the Kirkland Signature brand. A 14-pack of Kirkland Signature triple-blade razors sells for $23 ($1.64 each) while a 12-pack of Gillette razors sells for $12.59 ($1.05 each) at Walmart.

15. Soda

Soda will typically be cheaper at the grocery store, especially if you use coupons or take advantage of in-store promotions like two-for-one deals, according to Reader’s Digest.

16. Nuts and Seeds

Nuts and seeds only last for a couple of months because they both contain high quantities of oil, which causes them to spoil, according to Eat This, Not That! Even if you get a good deal on these items at Costco, you might end up having to toss a lot away, which makes the deal not worth it.

David Tonelson / Shutterstock.com

17. Coffee

Coffee tastes best when the beans are recently roasted, and that certainly won’t be the case by the time you get to the bottom of the bulk beans you bought at Costco. Plus, coffee is relatively cheap even if you don’t buy in bulk, so you’re better off just buying it in a quantity that you can finish within a week or two.

18. Hummus

Costco-sized tubs of hummus are too large for the typical household to get through before its expiration date.

19. Kirkland Gel Dishwasher Detergent

Consumer Reports rated the Kirkland Signature Gel dishwasher detergent as one of the worst buys at Costco. Consumers said the product was ineffective at getting dishes, pots and pans clean.

20. Memory Foam Mattress

Costco’s Ara 13-inch 100% Visco Memory Foam mattress was also rated a product miss by Consumer Reports. It was rated low for back-sleepers and was only rated “mediocre” for providing stabilization.

21. Sunscreen

Check the expiration date on any sunscreen product before buying it. It might seem like a good deal, but if it goes bad before you use it, it can do more harm than good.

22. Rice

You can usually find better deals on rice at an ethnic market than at Costco. YouTuber Flo Lum reported that a 25-pound bag of Jasmine rice cost her about $40 at Costco, but only $14 at a neighborhood Asian market, according to Money.

23. Shampoo and Conditioner

Look for deals on these products at chain drugstores, grocery stores and Target. When combined with coupons, you can usually get shampoo and conditioner for a better price than you would at Costco.

24. Beauty Products

Beauty products have a shorter shelf-life than you might think. Liquid face makeup lasts six months, mascara last three months and skin care products last six months to a year at most, according to Good Housekeeping. Buying large containers or multipacks of beauty items will likely mean you won’t get to use all of the product before it expires.

25. Electronics

Don’t assume that Costco will always have the best deals on electronics. Be sure to comparison shop for the same item at Best Buy, Walmart, etc. before hitting the check out.
