Oh, I know, I've dealt with the scammers before. I've never known a scammer to use paypal though since it's trackable. I always love the line "hello, I'm very interested in the product you have for sale and would like to buy immediatly! Please tell me all you can about this product and I will send you a cashier's check plus $4000 for you to pay my shipper, then you just send me back the cash difference"
A little tip: if the english gets more and more broken with each contact RUN!
