To celebrate the return of their sweet potato fries, use this White Castle coupon to get free sweet potato fries with any purchase. The freebie fries are the super saver size (I'm guessing that means teeny tiny). The sweet potato fries come with a new cinnamon dipping sauce. Coupon expires Nov. 30, 2010.
The fine print says one coupon per customer per visit.
Check back later today and through the week for more great deals at WalletPop.
