What to Buy At Costco

What to Buy At Costco

Editor’s Note: This post has been around for awhile, so I’m updating it today in the fall of 2021. Not only have our eating habits changed, but I got our team to weigh in this round, too. Happy shopping!

It’s not breaking news to say Costco can be a lifesaver. I mean, where else can you buy car tires, a new TV, and a 50-pound bag of sugar all at the same place where you get a hot dog and a soda for $1.50? What a great time to be alive!

That said, Costco can be horribly overwhelming if you go in without a plan. Also, you might leave wondering, “Was that really a deal?” Here is a list of things we think are definitely worth the price of admission. We would love to hear if you agree.
