Walmart is developing its own paid membership service to compete with Amazon Prime.
The only details released about Walmart+ was Walmart Chief Customer Officer Janey Whiteside with the lead on this project.
I believe Walmart+ will offer storewide discounts especially on Walmart brands like Great Value, George, and more. I also expect Walmart+ to offer free same-day grocery delivery. Anything outside of that would be a bonus for the future subscription service.
