Sellers beware- I had something for sale and got a couple of responses that were scams.
One was a woman claiming to represent an international company who she claimed hired her as a buyer and said she would be sending her son for the purchase.

The other was a paypal scam. A man insisted on paying by paypal and wanted me to sign up. He said he was a marine engineer on a ship and wanted to give his brother a surprise birthday gift. He was going to pay me more than I was asking. I googled part of his letter which was almost identical to this posted scam:

Watch out for this information:
His name on the e-mail is Mathew Visent and his e-mail address is:[email protected]
After I told him I don't have paypal and can not get it here, he wanted to wire me the money.  That is the second way to carry out the scam.
In both cases I insisted on cash and haven't heard back from either of them. Please be cautious. I have posted this only to serve as a precaution to sellers and buyers.
