Wow nice card! Sure you want to part with it? Problem is used electronic goods are sometimes hard to sell (probably not that card but when they start to age I found them hard to unload) and a card like that is usually worth more than someone will be willing to pay for it. Here is what I would suggest.
Like prozac said try the forums you might find someone in your area who wants it. (I don't know your age but be careful of crazies they are out there)
If you find a buyer meet them in a public place like your local police station for the exchange
Do you have a local bargin hunters paper in your area (might be called a Pennysaver)? They often let you advertise for free if the amount is not above a ceratin amount.
Try a family member or friend! Or someone at work! Good luck!
An add in the paper can cost 15-25 dollars per week so try to use free advertisement if you can. Use you local grocery store bulliten board!
