Wendy’s is offering fans of its famous Frosty a deal as the summer winds down.

The fast food chain is charging $1 for the small size of its famous frozen treats.

Until Sept. 15, customers can buy the Classic Chocolate Frosty or the seasonal Triple Berry Frosty, which contains strawberry, blackberry, and raspberry flavors, for $1 at participating Wendy’s restaurants while supplies last.

Is the Vanilla Frosty returning to Wendy’s?

The Vanilla Frosty could be headed back to the Wendy’s menu.

In late August, food blogger Markie Devo announced that the fast food chain would start phasing out its Triple Berry Frosty to replace it with the Vanilla Frosty.

Wendy’s first introduced the Vanilla Frosty in 2006. Since then the frozen treat has been a rotating menu item for over a decade. The fast food chain brought the treat back earlier this year before phasing it out for other seasonal versions of the treat.
