As a new member I feel it only fair to warn you that local promos normally trade/sell for $5. They may go higher when they first come out, but I would not be lured into trades that are excessively skewed in the other guy's favor. As much as I would like to think that everyone on these boards will trade fairly, I have experienced otherwise. If you are not sure whether a trade is fair, just post the offer here and you will get responses quickly. I woud caution you not to do all your trading through PMs since that is where the problems that I have had usually occur.
These guidelines will fade over time once you have experience on the boards and understand trade values better, as well as general supply and demand issues.
