The deal is only good at Supercenter locations (i.e. the bulk of their locations) and you can choose either a vanilla or chocolate cupcake with either white buttercream or whipped icing. You can use their website to see if your local Walmart is a Supercenter.
According to the company, the freebie is meant to celebrate "everyone's special day regardless of the day you were born."
