I'd call sears from here first. If I'm not mistaken we went to Buffalo 2 years ago and my DM used hers there. It comes back like your visa with the exchange rate on the bill.
I use mine everytime I go down because the only place I seem to be able to find clothes is the Sears in Florida at the Altamonte Mall. I have also used it at the Sears in Buffalo. I used mine in Florida in June of the year.
