There are lots of websites from which you can print coupons, but I find that my best coupons come from the Sunday paper...I enjoy reading it, it only costs 1.50, and I save WAY more than that with the coupons I get from it. Also, you can contact ANY company and request coupons, and some of them will just send you a bunch...I do this with products I like. Also, whenever there is something WRONG with a product I buy (food or household, fast food, anything) I always contact the company, and they always send coupons for free products.
My best advice with coupons is cut only the ones for things you would normally buy (it's not a deal to save a quarter on something you wouldn't have bought otherwise) and then see if they are on sale...extra savings. It works great. I save at LEAST fifteen a month off of a $100 household shopping bill (stuff that isn't groceries) and probably twenty or thirty on my monthly grocery shopping...and that's just from the paper.
