Free grocery coupons can be found on coupon websites, such as Coupons.com and The Krazy Coupon Lady, as well as the websites of specific retailers, such as Wal-Mart. Users can print the coupons from these sites at home, and some sites also allow users to save coupons to mobile apps instead of printing them.
Coupons.com offers printable grocery coupons grouped by category, and users can also search for local coupons or offers linked to a store's membership card. The Krazy Coupon Lady website has a database where users can find grocery coupons by name, store or type. The Wal-Mart website's printable coupons section groups grocery coupons by brand and category.
