You can buy, sell, swap or trade with other in your area.
I was getting the good old fashioned Nigerian scam.  They tell you they want your item then at the last minute tell you someone owes them money so they will have this 3rd party pay you with a money order or check of some kind for more then your asking price. this extra amount is to cover the shipping cost then any left over you will repay them later.  of course the check turns out to be fake and the bank holds you responsible.
