Is there an app where coupons are delivered to your smartphone?

Groupon and Coupons.com provide mobile apps that deliver coupons and deals straight to a person's smartphone. These companies also have Internet websites that send emails with the latest deals that can be viewed on the phone.

Groupon sends registered users emails every time new deals come up, and a smartphone user can specify location and other preferences to get the most appropriate offers.

Coupons.com provides a list of companies that offer smartphone apps that can send coupons directly to the phone as well as a list of coupons on its website that can be emailed to the user's phone or printed right from the website.
