These scammers always want you to ship RIGHT AWAY. So they have the item when you get stuck for a bad payment.
Change your ebay prefs in your account to US ship only, and require immediate payment from a verified paypal acct. You can set all kinds of things in the prefs area to keep scammers from even bidding in the first place. Just do it.
Also, scammers are now sending a fake paypal email saying YOU HAVE FUNDS. But when you go to you paypal, no payment was made. Its a fake paypal email. Paypal NEVER sends emails saying YOU HAVE FUNDS. Don?t fall for that.
Ebay is a scammers paradise today. And ebay could care less cause THEY are making $$$, while YOU get scammed. They just don?t care.
Notice how lately ebay raised fee's, and now require you to use their shipping tools, while they DO NOTHING to help protect you from scammers. 
I'm just waiting for the fed gov to close this racket called ebay down for good. Selling hot merchandise, scammers galore, and no real attempt to stop this on ebays part. Why? They are making big $$$, they don?t care about crime and scammers.
