Through April 20, Burger King is giving away free Whoppers (with a catch). Here’s how it works:

  • Check out the Burger King Facebook page every morning.
  • Look for the student offer of the day.
  • Answer the school question to get the promo code.
  • Download the Burger King app and click “How Much Do You Know?” (I found it under the trending tab.)
  • Enter the correct answer to get a free Whopper with any purchase.

Please note that you must use the BK app to get this deal. Order for pickup, or get free delivery on orders of $10 or more.
