Guess everyone gets their fair share. I have a guy right now wanting to know where to send his check even though it specifically states paypal only.:disgust:
It's up to you how you want to deal with him since you did state in your auction only to US and Canada. If I was in your situation, I'd start by assessing his feedback, then find out if you are comfortable with taking paypal from him. If you aren't, there's always bidpay, which is a safe way to go.
My auctions, I ship international but if you buy through me and want it international (yes, even Canada since the address isn't verified) you are going to pay alot for shipping, I include a "self-insurance" fee so that if I ever get scammed I'll still have made up for that.
