Participating Burger King restaurants offer a Whopper or Hershey's Sundae Pie for free with any $10 delivery order via coupon codes "VALPAK3" and "VALPAK4". (You can only use one coupon per order.) That's the best freebie with purchase deal we've seen from Burger King Deal since June when we saw Buy one Whopper, get the second one free. Delivery is available at select stores in VA, MD, FL, NY, TX, CA, CO, NV and IL. Deal ends August 31.
