Are you feeling a bit frosty? Everyone loves Wendy’s popular frozen treat — the Frosty. Even more so, now that the fast-food chain has introduced seasonal flavors on the menu. And, this spring, the flavor of the season is Thin Mints. The limited-time flavor combines the Classic Chocolate or Vanilla Frosty, swirled and topped with a rich, minty cookie crumble sauce — inspired by the flavor of Girl Scout Thin Mints.

I wanted to try a Thin Mints Frosty as my free Frosty Jr. with a physical key tag and purchase recently, but they refused, saying they did not have the Thin Mints Frosty in the Junior size. I later checked my Wendy’s app and they were right. So this is a chance to try the Thin Mints Frosty at an overall discount. There is also some game on the Wendy’s app about trying to complete a pipe system for prizes, but one also gets a sweepstakes entry simply for trying.
