Coupons

So,I'm trying to get more into couponing,but not to an extreme to where it's unnessecary amounts of food,and drinks like in Extreme Couponing.I'm always looking at the newspaper ads,and the coupon ads.I've just started going on a few websites,and printed some out.I was wondering if anyone had any tips for couponing,if so,just comment on the post!Any would be great!
