I'm selling a Fendi I've had around for awhile, and started the bidding low, which has generated a lot of interest (thank goodness!). But the most recent bid is from a user who's less than a week old, and has bid on 29 other designer sunglasses/purses. Should I block this bidder and cancel the bid? I've had such a run of bad luck with NPB's lately....is it worth it? Or could I just end up ticking off a legit eBayer?
