I have just won an item on Trademe but unfortunately postage was not known at the time (an approximate courier fee was quoted). The Ping amount was for the Auction item alone. To make payments easier in the future, is it possible to allow the vendor (or buyer) to add the actual cost of postage to the purchase amount after the auction has ended? I certainly understand it would be difficult for the vendor to quote accurate postage costs when yhey dont lnow where the winning bid will come from. In my current situation (living in Aus), I cannot pay with Ping because there is only my winning bid...
