Free Garlic Cheese Slider at White Castle! (While they last)

It's another freebie for liking someone on Facebook today—and this one's pretty tasty. While they last, White Castle is giving away a coupon for a free Garlic Cheese Slider when you like them on Facebook. Head here, log in to Facebook, then click the 'Like' button. You'll be asked your first name and phone number, then get access to the coupon. Apparently some folks have been confused when the coupon prints as it doesn't really look like a coupon and has no bar code. But according to a post by White Castle on their page you should rest assured: the printed coupon looks just like the graphic promoting it on the page, just with a “magic coupon code” that will work at the store.
