I don't think there ever was a commercial, WTA, (or at least one that aired) but if you clicked on the link to the "Save Money Live Better" link there was a small video screen playing the Band of Whorses (Thanks Stereogum!) song on that page.

Band of Whorses also turned down licensing the song in a commercial just last week - not as a principled stand against the Blackwater/Halliburton of the retail sector but caved to the pressure he got from fans.
