When you buy it in quarts - it's the liquid version. So you have to whip it up yourself. Saves on space and it's not too hard to whip up. You just thaw in the fridge overnight and whip it up for about 5 minutes in a cold bowl.
I live in Canada and I have been to both Costco and Sam's. Costco wouldn't sell me anything,and thought it was a strange request(???). Sam's will sell me Dawn's whipped topping and buttercream....It is in cartons frozen and I had to get 4 of them(2 litre cartons). The man at the counter was very chatty and gave me a weath of information ,even let me and by BF sample it...MMM
Anybody use the Dawn's version of the whipped topping? I assume works the same as Rich's.
