I haven't seen anything yet either. All of my accounts have some policy in place where they call us. It actually got annoying when my wife was "couponing" and we hit 5-6 stores in a couple hours. Always got a call. Comforting. Any charge in another country is set to be a flag. When we travel we make a call and let them know so it doesn't get flagged.
