Burger King: 25¢ Small Hot or Iced Coffee (2/18-3/10)
Through March 10, you can get a small hot or iced coffee for just 25¢ at participating Burger Kings. Price excludes flavors and whipped topping. Also prices may be higher for HI and AK.
I typically think that making my own iced coffee is much cheaper than buying it but wow, this might prove me wrong.
