I have a bag up for bid now, not even a terribly expensive bag, one I have listed at what I consider to be a great price. I initially listed it with a BIN $25 over the starting bid. A buyer bid on the bag, thus cancelling the BIN. Then this buyer emails me and makes me an offer of $50 less than the BIN (plus no shipping) on the bag. I'm like...weeeell, you just bid at the starting price...why should I now cut a deal? I refused to lower the price, especially because the bag has a number of other watchers. The buyer (zero feedback btw, who I can usually work with) emails me back today with a long rant about how she's a "serious eBayer" and she doesn't have time to play these bidding games, most sellers make second chance offers anyway, why won't I just sell her the bag now? She just doesn't seem to understand that she's already agreed to pay a higher price for the bag I've never had to block anyone before - should this be my first time?
