Dear XXXXXXX,

do you ship to Canada? if so, USPS ground would be fine, how much to postal code T6J 7B3?

Dear *the_worm*,

For the last time:
NO INTERNATIONAL BIDDERS OR BIDS WILL BE ACCEPTED UNDER ANY CIRCUMSTANCES. DON'T EVEN ASK. I ALSO WILL ONLY SHIP TO CONFIRMED U.S. PAYPAL ADDRESSES.

I guess this guy must get lots of interest in his auctions. I would think that would be a good thing....
