I have an item for sale on auction to end next Sunday. I have had a couple of people contact me to ask if I would do a buy it now price. My question is, if I revise my listing to a buy it now, do I incur a fee? I have only contacted the first person that contacted me so far, and she is happy to pay the price I asked and said she will pay via PayPal if I take down the listing. Is this against eBay rules? If we do it this way, is it safe, I seem to recall that a buyer can reverse a transaction then claim not to have received the item, is this the case?
