You can choose up to three different flavor for the "wings."
The promotion runs through November 20, 2018 at participating locations nationwide.
For comparison, while my local Wingstop doesn't offer a 25 order of wings, a 20-piece order of boneless wings (with up to three flavors) is $16.28, while a 30-piece order is $24.29. Dips are normally 89 cents each in my area (may vary).
