We want to know your favorites, too. Comment below with your top Costco buys.

1. Bread

Bread is one of those staples shoppers often pick up at Costco. The loaves come in larger packs, and freezing the extras makes it easy to stretch your purchase.

Besides bread, Redditors said their Costco must-buys include bagels, English muffins, tortillas, and other picks from the bread aisle.

2. Coffee

Coffee is a popular item at Costco and is frequently mentioned by people. Members like having Kirkland and name-brand options. You can get a large bag or container at Costco for much less than what you’d pay at the grocery store.

3. Premade Food

Many Reddit shoppers swear by some of the premade meals, such as casseroles, meatloaf, soups, and more. Picking up these dishes takes the stress out of dinner when you don’t have time to prep dinner.

4. Eggs

So many people listed eggs as something they always buy at Costco. Some Redditors mentioned they always buy the hard-boiled eggs, since it’s a convenient option.

5. Costco Optical Items

The optical department got brought up numerous times by Redditors discussing their top picks to grab at Costco. The mail order contacts have some of the cheapest prices, and you can get glasses for cheaper than at many eye doctors.

6. Kirkland Paper Towels

Kirkland paper towels were one of the most talked-about household buys among people. I personally buy Kirkland paper towels because they’re good quality and cheaper than name brands.

You may be wondering why paper towels are on this list and not toilet paper. Kirkland toilet paper had varying opinions from people in the Reddit discussion. Some mentioned it as a must-buy, while others complained about the quality.

It may be one of those items you’ll have to try for yourself to see if you like it, but the paper towels are definitely worth buying.

7. Bakery Items

The bakery is known for its sweet treats and crowd-pleasing desserts. One clever shopper suggested buying plain sheet cakes and decorating them at home. This could save you some money when you need a birthday cake or dessert for other celebrations.

8. Vitamins

Costco carries a decent selection of vitamins, which many Costco shoppers mentioned as something that always ends up in their cart. Whether it’s Kirkland or name brands, Costco is an affordable option for vitamins.

9. Vacation Packages

Vacation packages are a lesser-known part of Costco’s offerings. Some members mentioned booking trips through Costco, which saved them a significant amount of money. This one surprised me because I’m a Costco member and didn’t even know about this.

10. Vanilla Extract

Costco’s oversized bottle of vanilla extract is a bargain, so it’s no surprise many shoppers grab one. Some shoppers also mentioned picking up vanilla beans, which can add even more flavor to your recipes.

11. Kirkland Brand Bacon

Kirkland’s thick-cut bacon was mentioned repeatedly in the discussion. While Costco offers other types of bacon, the thick-cut variety was the one people couldn’t stop raving about.

12. Dog and Cat Food

Pet owners often stock up on food and treats during their Costco runs. The larger bags and boxes mean fewer last-minute trips to the pet store.

Besides treats and food, people also mentioned other pet items like toys and litter. One Redditor said cat litter alone justified the price of being a Costco member.

13. Nuts

Nuts are a pantry staple that many people always buy at Costco. Larger containers work well for snacking, baking, or adding to recipes. If you don’t go through a big bag fast enough, you can always freeze it for a longer shelf life.

14. Gas

Gas is one of the most consistent perks of having a Costco membership, according to shoppers. Many people fill up during their regular store visits. While you might have to wait in line, the cheap price makes it worth it.

15. Gift Cards

Gift cards are a practical buy for restaurants, entertainment, and more. They’re often sold in packs, making them useful for gifting or personal use.

One person noted that Costco sometimes runs sales on Southwest gift cards, which can make traveling cheaper.

16. Hearing Aids

Costco’s hearing center offers hearing aids at competitive prices. One member mentioned great deals on hearing aids, which can be a big purchase. If you wear a hearing aid, it’s worth looking into.

17. Food Court Items

It’s no surprise that food court eats, drinks, and treats are loved by Costco shoppers. Many Reddit users mentioned their favorites were the hot dogs, pizza, and ice cream.

18. Clothing

Clothing is another section worth checking out. Basics like socks, jackets, and shirts are stocked year-round alongside seasonal options.

19. Kirkland Pesto

Kirkland pesto is a staple that many shoppers said they always grab. It’s an easy way to add flavor to pasta, sandwiches, or other dishes. This is my favorite too, it’s delicious and a good deal.

20. Over The Counter Meds

Over-the-counter medications such as pain relievers and allergy pills are popular picks for Costco shoppers. The larger bottles are often much cheaper than at stores like Walgreens, CVS, or Target.

These Costco buys came from this Reddit discussion where people shared their favorite purchases.
