To be honest, I don't use many coupons. It's not because I don't think they save money; they do. The reason I don't use many is because I don't buy most of the products there are coupons for.
I went so far as to go to a coupon page - you know, the ones that list coupons for your area. You tick the ones you want then print them off. I went through five pages and found one coupon that I might use.
What don't I use? Pet food, frozen dinners, high priced toilet paper, paper napkins, paper towels, cold cereal, disposable diapers, refrigerated biscuits, air freshener, bottled tea... well, lots of things.
Most of those things have been created in the last few decades. I'm of the old school, I guess. I didn't need them 40 years ago and I don't need them now.
Now if they had coupons for flour (store brand), sugar, baking powder, loose leaf tea, vinegar and so on, I'd use them.
