Frustrating Amazon

Some days Amazon just drives me batty. Part of it may be the fact that I have 3 distinct accounts on Amazon, all with the exact same login, but which one I get depends on on what password I use when I log in. One of these accounts gives me the discount for using A9, the rest don’t. Depending on which one I logged into last, my A9 search history is hosed. The wishlists are in various states of upkeep, and all different. It’s confusing and frustrating and really turns me off from Amazon. I wish I could just delete all those accounts and start fresh. (If they let me export my wishlist first.)
