This archived spring promotion was active previously but has NOT been confirmed for 2025. I will keep watching to see if it or a similar offer returns. As soon as I receive further information, this page will be updated. Be sure to check back often!
White Castle’s Slider-bration has arrived! Celebrate National Hamburger Month with original White Castle Sliders for just a quarter each! There is a catch, however: the 25 cent Slider event is not happening at all White Castles and it will only be held for just 2 hours at each location.
This event kicked off in Columbus, Ohio at 12:01AM EDT on Wednesday, May 1. It will move to a new White Castle every 2 hours, continuing through May 31.
The first time I went to White Castle was 1982 and hamburgers (then called simply “White Castles”) sold for 24 cents each. Last time I checked, they were up to 69 cents. So, this basically rolls back 31 years of gradual Slider price inflation. Don’t miss the White Castle Slider-bration!
Offer valid May 1-31, 2013 at participating restaurants. Limit 10 discounted Sliders per customer. Most White Castle locations will be open regular sale hours on Mother’s Day (Sunday, May 12) and open holiday hours on Memorial Day (Monday, May 27.) Many are open 24 hours.
