Shake Shack Center City (2000 Sansom St.) is giving last-minute holiday shoppers more incentive to get gifts and support local businesses with a new promotion running from today, Dec. 15, until Dec. 31.

Shoppers who spend any amount of money at Knit Wit (1719 Chestnut St.), aoki boutique (115 S. 22nd St.) or ellelauri (114 S. 19th St. and 1625 Chestnut St.) can present their receipt at the Shake Shack counter for a complimentary Salted Caramel Hot Chocolate drink. That's a tasty treat too perfect to pass up.
