I'm sticking to my guns on this one...

My husband recently bid on a ceiling fan on eBay, using my account. The auction was a week long and there was no reserve price on the item--the starting bid was $20. The auction was won at $50 (he REALLY wanted that fan) and the listed shipping was for a little over $5. I thought the shipping seemed low, but I wasn't going to argue, since it was a great deal, and I thought maybe it was being shipped at the slowest, lowest price. Whatever, it was my husband's bid. I got the email saying I'd won the auction and promptly paid via Paypal.

A few hours later, I went through the following series of exchanges with the seller:

( I know you already paid me, but could you send more money? )

Now, I just sent this a short while ago, so he will probably continue to be an ass, but I might get lucky and have him give up on the correspondence. I don't expect to get the item at this point, but I will at least have my say. I don't think I am the one in the wrong here. What do you think?
