I never count my chickens till they hatch...
You have to realize this day and age, people have completely done away with caring in general. Whether its your feelings, how they look in others eyes, what their word means, etc It doesn't make them bad people or dishonest people. Its sad but its also something you need to come to grips with and capitalize on. When people list items for sale, I dont care what they say, that item isn't really sold until money is in their hand. All deals are on until its sold, cash is king. If you want it bad enough, go get it now. Otherwise, its your own fault, not theirs. I think if you start looking at it that way, you'll land more deals and have better experiences with these ads. Also realize there are always backdoor deals going on in the PMs
