So, all the times that I lose an ebay auction and get a 'second chance' offer within an hour or two--that's just them bidding on their own item to rip me off, right?
The time frame it happens is also important. If it's within a hour or two, yes. If it's a DAY or two later, though, then it's probaly legit. I've had sellers cancel bids for stuff of mine they won.
