Seller doesn't accept paypal, should I be worried?

If the auction stated that they take paypal and now they are saying they won't you can file "thingy" through pay pal, a mutual withdraw for the auction because he now won't take it. If the auction stated that he wouldn't take paypal you are under the obligation. Personally, I wouldn't send a money order for over 10 bucks-to many scammers!
