if someone makes a deal here to buy or sell then backs out before anything changes hands , then what's the big deal?
Spend your money on someone else, there are plenty of good sellers here.
Also, I had two people here that agreed to buy things then backed out without even telling me, after a couple of months, I just relist it or sell it on EBay,.
Sheesh, what do you want for free!
I for one, am extremely grateful for this forum and the valuble service it offers and at almost no profit to the creator.
