White Castle’s Free Original Slider

Now that we’re already on the topic of sliders, let’s talk about the home to The Original Slider and America’s first fast food hamburger restaurant, White Castle. Not to be outdone, this iconic brand is also celebrating the National Slider Day. On May 15, White Castle announced that it will be treating customers to a complimentary Original Slider—no purchase required!
To cop up this exciting deal, all you need to do is use the digital coupon available on White Castle’s website or social media channels or enter the promo code “SLIDERDAY” on the White Castle app to redeem the offer. But that’s not all, because the brand is running another deal: six Original Sliders for only $4, which was launched on May 9 as a way to keep fast food satisfying and affordable. This discounted offer brings the price of the Original Sliders to just 67 cents each.
This National Slider Day, vice president at White Castle, Jamie Richardson, also recalled how the introduction of Slider put White Castle on the map of top fast food chains. The Original Slider was introduced over 100 years ago, and in 2014, it was recognized as “the most influential burger of all time” by Time magazine. In 2015, White Castle introduced National Slider Day as a tribute to its Original Slider. Since then, the brand’s selection of sliders has grown significantly, and it now includes Bacon and Cheese Slider, Double Cheese Slider, Breakfast Slider (with fresh cracked egg), and so much more.
Again, don’t miss out on the deal for the slider that started it all. Grab your free Original Slider from White Castle on May 15, online or via the app!
