McDonald’s has become notorious for its broken ice cream machines – there’s even an independent website that monitors broken McFlurry machines. So Wendy’s is taking advantage.

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 taking shots at the Golden Arches by advertising its $1 Frosty as the go-to sweet treat while the “other guys” struggle with broken ice cream machines. Without mentioning McDonald’s by name, Wendy’s added its locations to a so-called McBroken map that tracks the chain’s malfunctioning ice cream machines.
