Coupons.com

Why the experts like it: Coupons.com offers as wide a variety of timely coupons as you’d find in the grocery shoppers’ gold standard: the Sunday paper, says Dworsky. Phil Lempert, founder of news site Supermarket Guru, praises the site’s simple layout, which makes it easy to browse available coupons, and then print them out for in-store use. Enter your zip code for area-specific deals. There’s just one minor drawback: “There are still some retailers that will not accept Internet coupons,” cautions Lempert. Check that your supermarket does so before downloading the site’s coupon-printing software.
