I can almost guarantee you are going to get scammed. Ebay will give you 0 support if you pay with bitcoin.
Cheers, that's what I figured tbh. Especially since the seller made no mention of increasing his BTC price after the recent ~30% drop in USD value.
Although he has triple digit 100% positive feedback, who's to know how many neg feedbacks were disregarded in the past if the disputes all went in his favour?
Still, some more advice would be appreciated, especially if someone has successfully resolved a dispute of this fashion...
