Through March 10th, Burger King is offering up Small Hot or Iced Coffee for just 25? – yep, just a quarter! Keep in mind that this offer is valid at participating locations only and excludes flavors and whipped topping (and does not appear to require a coupon), so call ahead to make sure your nearest Burger King is participating!
