Be aware of phishing on this site. If you've been contacted by "Sammy Fishers," don't send him money. He is a confirmed fisher.
He'll ask that you and he do a transaction through Paypal, and then he'll send you a highly professional "Paypal" email saying that he has deposited the value of your item plus extra to pay for delivery, but that the money is being held until you send money to the delivery service via Western Union, and you provide the MTCN number. If you sent to the delivery service, he's won.
If Sammy Fishers got you, or tried to get you, let me know.
