Websites such as Coupons.com publish grocery coupons which shoppers can print wherever they have access to the Internet and a printer. The products available on these sites are national brands found throughout the United States.
Some sites, such as SmartSource, require special software for printing coupons. That software is available directly on the website. The Krazy Coupon Lady, Hip2Save and other blogs provide guidance on current deals. They offer instructions on how to maximize savings for each deal, as well as links to the coupons needed. They also occasionally post links and instructions on entering drawings to win free merchandise or receiving free samples of products.
