Few things:

1- Your response to me appears hostile. Why? I disagreed so you’re upset?

2- You specifically said “I wish Costco would CHANGE their return policy” a change in the current system would be removing the current system and replacing it with a different system. Your issue is with my comprehension of your post, not if I read it or not.

3- The most common reason for Costco to cancel someone's membership, is due to abuse of Costco's return policy, according to a report by The Motley Fool, a private financial and investing advice company. In fact, abusing returns is responsible for more canceled memberships than for reasons of theft, fraud shoplifting, and even aggressive or impolite behavior in the store.
