This app absolutely SUCKS! Today for the third time a buyer has agreed to an buy an item from me, negotiated a price and set up a meeting place and time only to back out at the last minute with yet another lame excuse. These wishy washy buyers suffer no repercussions whatsoever for doing this and all three times I had other offers that I turned down because I thought the item was already sold. Something has to change or I will never use this app again.
