A commercial floating around has revealed an upcoming event hosted by Walmart in celebration of Rainbow Rocks. A few select stores will be hosting it on various dates between the 14th and the 16th. If you want to invade a Walmart with an army, have the list over here. Expect giveaways, prizes, and the usual "why are a bunch of dudes here" looks as it happens!
You can also find the promo below the break.
Thanks to Mark for the heads up!
