You can generally tell which holiday is coming up based on the kind of candy you see. If you’re seeing chocolate bars and milk duds, we’re coming up on Halloween. If you see candy hearts, you know Valentine’s Day is approaching. And if you see candy canes made of peppermint, you’d best bet on Thanksgiving and Christmas. To match the coming season, Arby’s is investing in peppermint. Between now and when the offer expires on Tuesday November 13, you can get a FREE 20-oz. peppermint stick swirl shake if you purchase any combo meal. After chowing down on classic roast beef sandwiches (or turkey roasters, if they’re more up your alley), the shake is a sweet way to cool down.
