Through Groupon I bought ticket to Ripley's Aquarium in Toronto. I didn't notice in fine print that they charged me in US dollars not in Canadian. When I got my Credit card statement I found that I paid Groupon $ 7 Canadian dollars more for each ticket than I will be pay in Canada! What the kind of sale it is?! I lost my money. When I called Groupon they explained "Sales is final" no refund! Final sales?! Is it last item on shelf for sale?! Disgusting! Never using Groupon again.
