I never seem to find any good tear pads coupons around; does anyone know if stores put new ones out at a certain time (e.g. first of the month)?

Also, what stores do you find have a lot of tear pad coupons? It seems like the only ones SS has are "Coupon Zone" coupons, which expire within like a 2 week period... I think I've had the most luck with Zellers and Shoppers, and I don't think I've ever seen any at Walmart.
