24 Of The Best And Worst Things To Buy At Costco

Best: Cooking spray

According to The Krazy Coupon Lady, one of the best buys at Costco is cooking spray. The canola cooking spray at Costco costs about 15 cents an ounce, while at Walmart it’s about 27 cents per ounce and at Amazon, the PAM four-pack is about 46 cents an ounce. Costco is clearly your best bet if you’re looking to save some money.

Best: Half-sheet cakes

If you’ve ever had a Costco cake, you know they’re actually pretty good. As it turns out, they’re not bad on your wallet either. According to Good Housekeeping, the half-sheet cakes at Costco are typically about $10 or less, which is approximately half of what the same size sheet cake would cost at another store.

Best: Gas

While not every single Costco location has a gas station, if the location you frequent does, you should consider buying your gas there. According to Kiplinger, the gas at Costco is often cheaper than competitors in the same area. That being said, at some times lines can get very, very long, which means saving a few cents a gallon might not always be worth it.

Best: Canned tuna

Canned tuna is very versatile, so for a lot of people who are trying to eat filling foods on a budget, canned tuna is a pantry essential. According to The Kitchn, 16 (7-ounce) cans of Kirkland Signature White Albacore Tuna can be yours for about $35. It’ll help you fill your stomach without breaking the bank.

Best: Baby formula

Baby formula — like just about everything else needed to care for your babies — can be very expensive. According to HuffPost, if you’re looking to save money on baby formula, you should be buying it at Costco. Kirkland Signature baby formula costs about 50 cents an ounce, which is a total bargain.

Best: Alcohol

If you belong to a Costco, you probably already know that you can buy beer, wine, and spirits at some locations for pretty good prices, but those savings might not be only available to those who have memberships. According to The Kitchn, in some states, because of the liquor laws, even non-members can buy alcohol at Costco locations that sell it.
