In celebration of National Slider Day, WhiteCastle is giving out a coupon for TWO free sliders of your choice. It is valid at any participating WhiteCastle locations only on 5/15/2016. The coupon can be printed off of their official website.
The coupon states that it is valid for any single slider on a bun. It excludes double sliders, waffles, and toast sandwiches. I’m guessing that it means you can choose two single sliders. Remember, the coupon can only be used once per customer. No double dipping.
National Slider Day is 5/15/2016, and the coupon can be used on this day and this day only.
