Just had a bad experience on Ebay where I won a Top Try card for $41. While I was out, got home 5 hours later to find an hour earlier the seller relisted the item at $100. On asking was told pay on time. This guy did the same thing before to another guy
twice. A few further messages had him calling me names, threating to sue Ebay, saying he's heard about me doing this before ( ??? not paying within 4 hours I guess) amongst other things. It's not like I've lost any money over this, but my integrity questioned really gets my gander up. Will Ebay care, as long as the fees are coming in I would say no.
You can report the seller to ebay for not completing the transaction or abusive conduct.

If he gets reported a few times this will affect his Seller's level performance which ebay will hit them with extra penalties until they fix up their standards.
Hope this helps.
