Hey, I'm in Manitoba. Shoppers here have only insulins, however there is a pharmacy that caters to juicers (they even have books on the shit...) where it is no problem.
The funniest thing is I have a phat jug of winny that I draw with 21g's and shoot with insulins. The look on the pharmacists face when I ask for 60 21'gs hahahah...
Anyway, they are pretty cheap I think under .50 a piece. I would be happy to pick up for you next time if you want and ship them out to you (you pay of course!) if you don't have any luck locally.
My addy is on profile if you want to mail me.
