For meats and wine I find Super U cheaper usually. Certainly they take credit cards. They basically do NOT have US brands and frozen foods are labeled in French, so sometimes knowing French is an advantage. That, we just wing! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" /> The store is also SUPER clean. Carrefour, in particular (the Cole Bay store, which I know is not currently open), I have found to be not that clean. It seemed like every time I went in there, I smelled fish, which you should not smell anything, if the fish is really fresh. For carts at Super U, you can use a US quarter to put in the slot. Otherwise, they have smaller rolly carts which you can use. They don't provide bags, so you need to bring them or buy them. Although I think now, Grand Marche (Carrefour) also does not provide them? I don't remember.
