Burger King free Cheeseburger 9/18 with any purchase of $1 or more

On Sept. 18, in honor of the holiday, the fast food chain will be giving away free cheeseburgers to members of its Royal Perks rewards program with any purchase of $1 or more. 

The festivities don’t end there, though. Burger King is extending the celebration all week long, with different daily deals lasting through Sept. 24. 

On Sept. 19, guests who spend $1 or more will get a Whopper Jr. for free. The next day, Whoppers are just $3. 

Burger King keeps the holiday going, offering a BOGO deal on all Whoppers on Sept. 21, and a free order of onion rings with any purchase of $1 or more on Sept. 22.

To close out the week-long deals, they’re offering a $22 family bundle on Sept. 23 and double reward points on all purchases on Sept. 24.
