I only shop for 2, but buying in bulk saves me money. Here are 10 things I always get at Costco.

Paper goods can be expensive at my local supermarket, but at Costco, I find they’re a great deal.

Although I pay a little more to buy name-brand paper towels, I do purchase Kirkland Signature toilet paper.

As a household of two people with stomach issues, we’re picky about what toilet paper we buy. However, I think the Kirkland Signature version is comparable to the Angel Soft brand.

During my most recent trip, I paid $25 for 30 rolls.

When the average price for a dozen eggs rose to a record-high $6.23 in early 2025, I turned to Costco for more cost-effective options.

Now, I typically buy the 24-count of large white eggs for $4.83 and use them for breakfast, a snack, and a key ingredient when baking.

Another one of my Costco staples is laundry detergent. The warehouse carries a variety of brands, including sensitive skin options, which I prefer.

During this trip, I grabbed a container of Tide Free and Gentle Pods.

I also stock up on dishwasher detergent at Costco, which is typically stocked in both liquid and pod forms. I grabbed the Cascade Complete pods, which were on sale for $14, which I thought was a great deal.

My husband loves canned tuna and says that the Kirkland Signature albacore solid white version is better than other brands he’s had. He eats it on a sandwich mixed with mayonnaise or on its own with crackers.

As a picky eater, I eat chicken nuggets several times a week. I like to make the Dino Buddies version in the toaster oven and have them with a side of rice or pasta.

Some of my shopping is dependent on what’s currently available seasonally, or what novelty items are in stock.

On this shopping trip, I grabbed the Reese’s-inspired One-brand protein bars. My husband tries to consume as much protein as possible and loves Reese’s, so these were a quick yes.

I eat a peanut butter sandwich almost every day for lunch, so you can imagine how quickly we go through bread.

Costco carries Pepperidge Farm white bread as a two-pack, so I always grab that — especially because the cost for two loaves ($6.37) is similar to what I’ve seen for one at other supermarkets.

Drinks are another item that usually come home with me. For my husband, it’s typically Gatorade to replenish his electrolytes after working out, playing softball, or doing jiu-jitsu.

On this trip, I got a great deal on Starburst-flavored Sparkling Ice (on sale for $13) to help wash down a new liquid medication I’m on.

Costco carries Brami protein pasta in bulk, which is a huge win for me. This is the best-tasting protein pasta we’ve tried, and its consistency is actually pretty similar to regular pasta.

I like to put some tomato sauce on it for another easy way to increase our protein and fiber intake.
