Don't be discouraged. What has happened to you recently is probably a flash in the pan. I have bought and sold on the Collector's Forum for over 4 years now and have only had this type of thing happen once to me. My instance was just in the last month and it was a quoted price that was resonable for a piece I was looking for and when I agreed to the price the seller took over a week to get back to me and when the seller finally answered, the price had increased by quite a bit. I imagine that the seller after agreeing to the price decided they wanted more. I think it was Bob that said just hang in there because something else will come along and be a better deal at a better price
