I'm auctioning off an iPhone on eBay and have already had to cancel one bid from a user who was obviously a scammer. I'm a little concerned that when the auction ends the winning bidder will also end up being a scammer of some stripe. My question is, have you ever been in a similar position and decided to end an auction prematurely and sell to the highest bidder at that time (i.e. a legit-looking bidder with high feedback ratings)? Other than sacrificing potentially higher sales prices, are there drawbacks to consider?
