The only method to contact customer service is a phone number. After waiting an hour I was just dropped FOR THE SECOND TIME. I cannot get through. I am calling because my coupons never came that were supposed to arrive with my Costco membership. I did get through several months ago to discuss this issue and they said they would send them again, and nothing! I double checked and they have the correct address. I am horribly disappointed. I don't think I will use them again.
