The unofficial start of summer is here, which means people will be hosting barbeques and pool parties – and finally bringing out the all white.

On a typical day, the big box store opens between 9 a.m. and 10 a.m. (depending on location) and closes around 8:30 pm on weekdays. On Saturday, many Costcos open at 9:30 a.m. and close at 6 p.m. Sundays hours are usually 10 a.m. until 6 p.m. It's recommended that you check with your local store first to be sure they keep these hours.
