I'm been emailing a buyer about a purse I wanted to buy. I've had it authenticated on the forum already and she told me she was willing to sell it to me early on an agreed price. The problem is there is no buy it now on the auction. I want to purchase the bag through an actual auction so I can cover my tracks should anything go wrong. What is the best procedure in this case? Can they add a "buy it now" on an existing auction?
