I booked 3 different hotels through Groupon.com for my trip. I am from Canada and booked the hotels to stay in, in Canada. There is nothing that states the price is in U.S. Dollars. When I got my visa bill I was charged in U.S. Funds. Presently the exchange rate is 1.30 for every U.S. Dollar. When I called Groupon to ask why I was charged U.S. Dollars they said if I read the fine print I would have seen the statement about U.S. Dollars. I have been on Amazon, Hammachler Schlemmer, and Costco sites that all have Canadian and U.S. Sites. If I inadvertently was in their U.S. Site there was Warning that the site was U.S. Dollars. My complaint to Group On was solved with "read the fine print". Will never use the Canadian or U.S. Site.
