Buying Canadian coupons

I am interested in buying Canadian coupons. I am going to visit Canada soon and as I know, they stopped giving these Canadian coupons to foreigners. If I can’t get them there I wan to have some before I enter Canada. This is the reason why I would like to buy some online. Is there anybody who could help me with this issue? Please let me know. I have a great offer for you Canadian coupons. I would appreciate your help.
