Insider Details About Costco That Every Shopper Should Know

Costco is the world's second-largest retailer, and it’s a one-stop shop for pretty much anything you need. But, even if you’ve got a membership, you probably won’t be aware of all the inside details that’ll improve your shopping trips. We’ve got the secrets you need in bulk — including why workers really want to take a peek at your receipt as you leave.

1. The first store

The very first Costco, at the time called Price Club, opened its doors in 1976. Six old airplane hangars once owned by Howard Hughes were used, and it's still open today.

2. Millions of members

People love Costco, and memberships keep growing by leaps and bounds. In 2021, 111.6 million people were registered members. That’s a whole lotta bulk buying going on!

3. Rush-hour shopping

According to those in the know, weekdays from 3:00 p.m. to 5:00 p.m are Costco’s quietest times because most people are on the road. That gives you a free run to the latest deals and you won’t have to wait in line!

4. Original displays

In the early days of Costco, items weren't even taken out of their boxes and displayed on shelves and tables. In true warehouse form, everything was just sitting in stacks on top of palettes.
