I know you somewhat new to the site, but this is a big problem with some people and pay-pal. If you see it saying the money your giving him is a gift or a non purchase of goods, then the person on the other end of the deal is going to beat you for your money.
It should always have a very good description of what is going on, what is being bought, in what condition, when should it arrive, and for what make and model the seller says it fits, this way even if you get it and it doesn't fit or something, you can dispute it with pay-pal if the seller is not responding or avoiding you or sold you something different then what was agreed on.
Now I know this is a online site, but you should not have agrees to sending the money with the receipt saying the money is not for goods.
