I will NOT wear a mask. Asking us to wear a mask 4 month into a pandemic is like having us use birth control during my pregnancy. I am cancelling my membership and ask for a refund if my 6 month membership. I will protest your store as well.

Social Distancing Demonstrated throughout the store as well as while entering Costco. Most items are still well stocked however no sanitizing wipes.
