In Canada we have Costco and Sam's Club. The two major dollar stores I know of are Dollarama, which is based in Quebec and Buck or Two. There used to be one called Loonie Lizard, too but I haven't seen one in our area for some time. And, of course, there are always the independent dollar stores but they seem to struggle to survive.
In short, I think it all depends on where you live, what bargain stores you have. Some of the ones mentioned here like Mighty Dollar, I've never heard of before.
