Hi, just got offered something on Ebay thru the second chance offer system. The original buyer had pulled out and the seller had offered me the item on a buy-it-now. I paid via paypal and now the seller says the original buyer now wants to buy. The seller has now cancelled my purchase, even though I had already accepted and the offer and paid. Can the seller do this? (obviously they can because they have just done it with me!!) Forum's opinions are greatly appreciated.
