My paypal account was charged.
This is not a big deal hence the question mark in my original post but (and I'm retired so I have plenty of time to pursue this and be petty):
Based on the information I have there are two transactions:
1. Amazon sent me an unsolicited gift.
2. I paid for an item on ebay and have not received it.
So I should have two sets of earmuffs - if it really was a gift from Amazon.
If the "gift" from Amazon was really from the ebay seller why the duplicity?
