I have returned an item before on eBay where the seller refunded my money before I shipped it back to them. I'm in the same situation again(was sent the wrong item) and they want me to send it back THEN they will refund me. What can I do to make sure I get my money back? I will send with delivery confirmation, but if they say I did something to it or they never got it, I'll be in trouble. What steps should I take to make sure I get my money back???
