Where to find coupons

I am an avid couponer, though not crazy enough to be on Extreme Couponing! Really, in Canada, you can't practice couponing as freely as those in the U.S. (But if you know a way, PLEASE let me know!). However, I try my best to use coupons when the time calls for it. Wondering where I find my coupons? Here's a quick list of links for your reference:

-Pampers
-Huggies
-Think Coupons
-Websaver
-Save.ca
-Go Coupons
-P&G Brandsaver
-Heinz Baby
-Nestle

You'll have to join their mailing lists or make an account to get coupons/choose coupons, but it's not a big deal. Where do you find your coupons? Let me know!

P.S. Yes, I do have a coupon book! Best places to find coupon books? Dollar stores, baby!
