Costco stores won’t be open on Labor Day 2012 (Monday September 3), so pick up picnic cookout supplies ahead of time. Costco will be open the weekend before with their regular opening hours.
Costco will also be closed on two more upcoming holidays: Thanksgiving Day and Christmas Day 2012.
Though Costco (and Aldi too) will be closed on Labor Day, many other grocery stores will be open. Have a great holiday, everyone.
