Wednesday marks White Castle's National Slider Day, and fans of the infamous White Castle slider can visit participating restaurants for a free hamburger.

According to White Castle, customers can go to on May 15 for a coupon good for a few slider and soft drink.

For customers who visit White Castle wearing "western attire" on May 15 and every Wednesday while supplies last can earn two free BBQ Original Sliders with any purchase.

"At White Castle, we take tremendous pride in the 2x2 inch sliders we've been serving and perfecting for nearly 100 years," said Jamie Richardson, vice president at White Castle. "We invented National Slider Day as a special tribute to the fans who share that appreciation for the slider and share their cravings with us. We hope everyone will have the opportunity to bite into a tasty slider on May 15."

If you live in an area that doesn't have White Castle restaurants, it is offering $1 cashback through the end of May when customers buy two boxes of any four or six count sliders using the Checkout51 app.
