You can only get these deals if you have a paid Walmart+ membership, and unless I’m looking in the wrong place, it’s just a pretty random selection of stuff. But some of the deals are really good.
I didn’t see any Smart home stuff, but they do have some good deals on a few HP laptops.

Also, check Amazon, it looks like they have matched some of the deals, which surprises me. But if you have an Amazon credit card, you could then save an additional 5% in points over the Walmart price.
