Why Is There A Line Of People Outside Of Costco Before It's Open?

If you've ever showed up to a Costco before it opens to do some early shopping, you may have noticed a line of people already waiting to get in and wondered why they were there.

A Redditor explained the situation: "A lot of local businesses actually run off of Costco supplies [...] They get there as early as possible to make sure their stuff is in stock."

Businesses shop Costco’s bulk products for wholesale ingredients, food service items, and cleaning materials. They even offer Business Memberships for this exact purpose.

Many individuals also go early to get the best deals and beat the crowds. Costco stores tend to restock items overnight, so you’ll find the best stuff first thing in the morning.
