Found it, on Alipac, of all places, one of the sites that promoted the lie in the first place - won’t link to them:

Video: migrant workers in school buses at NC Wal-Mart

Update: A local Tea Party group has confirmed that these are not part of Obama’s illegal immigrant surge being bused in from the border right now. The group contacted a local farmer and found out these are supposed to be H2A migrant workers. Many thanks to everyone that helped us quickly track down the source of this video and dig in to find out the details about what was captured in this film clip! While these are legal immigrants, please remain diligent for Obama’s drop offs of illegals in your communities. Great work team!

Okay, so our ONLY evidence that Obama is busing in illegals, giving them EBT cards, and taking them to Walmart turns out to be nothing of the sort. But that doesn’t mean it’s not happening! Watch the skies Walmarts, everywhere!
