Your scenario is BS. You wouldn't get a strike, because the seller changed the ground rules and as a buyer, eBay would bend over backwards to take your side anyway. Be that as it may, are you really trying to tell me that most of the NPB strikes handed out are because of unscrupulous sellers? The little trading I do here isn't to make a profit, it is just to clear excess items and recoup a few dollars. If I miss out on a sale here and there, because of the type of scenario you put forward, I can live with that. It would certainly beat having to deal with the type of numbskulls, who bid on items with no intention of paying.
