I have a hot item for sale and already have a bid on it for slightly over retail - although I'm still out money between fees and shipping. I have an offer to pay with wire transfer for about $75 more with a buy-it-now to end the auction early from a buyer with great feedback. Should I negotiate for a bit more and end it early? I already have a bid on it? What is the safest way for me to get payment from her? And I'd like it to be quick so I can get payment before I ship. The item is about $800 and I really don't want to get scammed if someone bids it up for more.
