Walmart is having a free ice cream sundae event on May 22nd with Blue Bunny, Breyers, Hershey’s and Reddi Whip. The event is free from 11-4pm. And it looks like you get a sundae for free.

*NOTE: Walmart used to do these events all the time last year and the year before. I remember even stores that were listed would not have any idea about the promotions. I would strongly recommend calling ahead just to be sure.
