Cheapest Minoxidil in Canada?

What is the cheapest way to get Minoxidil in Canada? I know you can get it through US Amazon, but I've never done that so I'm not sure if you can put in a Canadian address? Total cost also doesn't seem to be much cheaper for name brand Rogaine anyway. Has anyone tried any of the other brand Minoxidils?

I have a family member in the US who will be visiting in a few months and I'm going to ask him to bring some maybe, but he doesn't usually bring a checked bag so that wouldn't be an option.
