Here are some other concerns:

You turn out to be a complete nut case. After receiving the item you email back that you don't like it (there's nothing wrong you just decided you'd rather not have it) and you want all your money back plus you want me to pay for the return shipping and you expect me to send you the refund first and you will ship back to me after you receive the refund. I politely tell you no. You start phoning me constantly and sending profane emails. You put my email address on spam mailing lists.

Was this a positive transaction I had with you? Do I do other members a service by giving you positive feedback?
