Description:
In short. Guy wants to buy items from me, the guy has very small rep on his profile, but from trusted sellers that i have happen to made trades with as well. I get the money, he gets his items, a day later i'm getting an e-mail that the guy is charging back. He succeeds and i am left without $370.00

I know there is no way of me getting my items back. But just a heads up to people who do paypal transactions. Don't make the mistake i did.
