In an icy dig, Wendy’s is offering customers a sweet “fix” to rival McDonald’s broken ice cream machines. Classic Frosty desserts are just a $1 at participating Wendy’s locations nationwide, for a limited time, according to the Ohio-based burger chain. The offer is good through Sept. 30 and no additional purchase is necessary.

Wendy’s is selling small-sized, $1 Frosty’s until Sept. 30 — and it’s collaborating with McBroken, which reports which McDonald’s locations have broken ice cream machines.
