I had this happen before with a U.S. seller. I was bidding on a old pocket watch. Not even the best quality but it had a horse on the cover which I liked. The watch was listed using Global Shipping and I eventually won the auction being the only bidder. With in a half an hour after winning the auction I received a message from eBay that my purchase was cancelled. I messaged the seller and I was told they didn't ship to Canada. Oh yes, I did contact the seller before I bid for some info on the watch and the seller was ok with my bidding then. With in 24 hours the watch was relisted with no Global Shipping but it showed shipping to the U.S. and Canada. Go figure. You can be certain my purchase was cancelled because the seller was not happy that the watch didn't go for more money.
