I'm generally liking Walmart+ and having someone trying (realistically) to curb the every increasing Amazon Prime cost is nice. I'm still kind of amazed that Target isn't doing a lot more in this space to remain relevant against both behemoths. I also like that there's a little more brand name stuff on Walmart due to them selling at least some stuff that they also have in store. Finally, at least for the last 2 years, Walmart is consistently 2-5 days faster delivery to me than Amazon. I know, I'm "special" in that I live in a rural forgotten area - but Amazon Prime used to get stuff here in 2 days from order, and then consistently made it slower and slower.
I like the gas savings (wish it was a more popular brand where I live of course). Most of the rest is vaguely interesting like most of Amazon Prime is vaguely interesting.
