Why does Costco close at 6 p.m. on a Saturday? Isn't that the busiest day of the week?

Because they believe in keeping families together, not at their jobs all the time.

Saturday and Sunday in America is considered the WEEKEND. only Monday thru Friday is consideref a BUSINESS day

Then go to Sam's Club they close at 8:30 on Saturdays too Sam's Club and Costco or exactly even in comparison price quality everything

Because their employees have families....

I wish they closed later as well.

Cause from Monday through Friday they do it by 8:30-9pm and they open on Sunday also which most of the similar businesses don't do it.

I hate that they close so early on Saturdays and Sundays.
