Decided to sign up for the Walmart + so I can take advantage of Paramount +. Among other things they have the Smithsonian Channel, which would cost me an additional $37 a month with my cable provider.
Occasionally, I buy something from Walmart.com that I can't find at Amazon, so I like the free shipping. Don't know about the other benefits since there aren't Mobil or Exxon stations in my area, and I am little too far from a Walmart for grocery delivery.
