For the month of September, with any Wendy’s purchase and payment through the Wendy’s app, get a free Dave’s Single at participating location.

“With the momentous holiday approaching on September 18, Wendy’s wants everyone to celebrate with a fresh never frozen cheeseburger,” the chain said in a statement. “And because one day of hot and juicy burgers is never enough, Wendy’s believes you deserve to celebrate through the end of the month.”

The deal will reset daily but can only be used once a day. Registration in the app also is required.
