Do you think this means trouble? I sold an item last sunday and waited for payment but there wasn't any so I sent another invoice yesterday which was ignored. I opened a case today thinking I might at least get my fvf back. Suddenly payment is made with no communication from buyer at all. I suspect the item has been bought to sell on which is fine by me but why would they only pay when a case is opened? and should I be worried about feedback now? Really annoyed. I hate this sort of transaction.
