I listed a pair of Hermes shoes I wore just once on ebay last night. A bidder is asking me for a buy it now price because she says she really wants them. I have 9 people watching, 0 bids so far. Is there any consequence to doing this? Should I still have her pay by PayPal, or is it better to do any method of payment? And what's a fair price to ask? The original price was $680, but I got them on sale for about $400. The shoes were worn once, and they don't have any major flaws except small scratches on the leather soles and the scuff marks on the bottom.
