I've only done two trades on this site. Both trades have been through the transaction manager. And, I have no complaints. Everyone is very nice, and very quick during the transaction. However, it did take a while for them to respond to my initial offer. Sometimes you have to be a little patient because people don't check this site every day. I try to understand that many of us have a job, a wife, a house, 2.3 kids, a dog, a cat, and what ever other priorities might be around. This is just a hobby we all enjoy that we do in our spare time, with our spare money. So hang in there and give them a little time. I'm sure they'll come around.
