Walmart is creating its own futuristic store that will ditch cashiers and the lines that gather near them, according to newly surfaced sources. The store is similar to Amazon Go, the online retailer's own cashier-free futuristic shop. The new store is supposedly codenamed Project Kepler and is the brainchild of Store No. 8, Walmart's own "innovation hub." The sources say that's only one of Walmart's current projects.
