Burger King is re-offering their previous deal of 10 BK Chicken Nuggets for $3. I think the regular price is around $6?
Apparently, you can get a free cheeseburger by doing a survey listed on your receipt. Also be sure to check out their latest coupons if you plan to buy anything else there.
The survey link is at the bottom of each BK receipt. Offer changes from time to time. Previously, free fries & drink. ATM, cheese burger ($3.90) Fill out the survey online and gives validation number. Take it back to BK and use with any purchase. Any purchase, cheapest thing on the menu is a 70c icecream cone. Plenty people leave their receipts behind so don't really have to even buy anything to get one. So works out at 70c for icrecream and cheeseburger, ad infinitum
Their new $2.50 Mint Chocolate sundae is quite nice too.
