With National Cheeseburger Day approaching on September 18, Wendy's wants everyone to celebrate with a fresh never frozen cheeseburger.  And because one day of hot and juicy burgers is never enough, Wendy's believes guests deserve to celebrate through the end of the month.

Wendy’s mobile app is offering free Dave’s Singles with purchase every day starting September 8 through the end of the month. This offer refreshes daily, allowing Wendy’s fans to enjoy a fresh, never frozen hamburger every day between September 8–September 30. 

One offer per customer per day. Registration in app is required.
