Figured I would ask this here since I don't have a lot of experience with this, but I put my SR MBP up for sale on eBay, and someone bought it using the Buy it Now, and they asked if they can send me payment through Western Union. They are a new account, but it says they are registered in the US. Is there any risk to this? From my understanding, once they send payment through WU and I pick it up, I have cash in my hands and there's no reversing it. Is there anything I should be looking out for here? I would appreciate any advice if anyone is more experienced on this type of thing.
