Tbf, that's a third party selling that box. But Walmart themselves do sell the Onn 4k stick/box which is the current every level pirates HW of choice to replace the firestick.

I have family members that have bought the Superbox in a Walmart physical store.

In fact here’s the conversation transcript of me asking about it:

Me: What was that piracy streaming box Uncle Gary got from Walmart? Superbox?

Them: Yeah

Me: Thanks

Them: I have it and I literally get everything for free. Like it already has the new super smash Brothers on it.

Them: Has every series and everything. I can give you the apps I have

Me: I dont need it haha just was showing people how illegal streaming is being sold in stores.
