But .... Why you are selling 10000 USD discounted by 60%!?
Because you're going to be an accomplice to a crime since obviously it's not his card but a skimmed one and most likely if you don't move pretty fast the funds will be blocked and your account reported also. If it would not carry any risk don't you think he would have done it himself or ask a friend? But with those risks, you have to make it tempting, so that's where the 60% comes from!
it will be interesting to see if anyone takes you up on this offer. easy $6000 profit. what could go wrong? 
It would be easier to list the things that can't go wrong!
Yeah well
thanks for clarification of obviouvsly things!Of course I am not going to buying anything but Just posting some Easy questions as evidence of the shady offer made by OP.
