What if they made Walmart be a giant vending machine, automatically fed with conveyor belts from a warehouse in the back?



This might not be true, but I think Walmart makes money by selling shelf space visibility to brands--e.g. General Mills pays Walmart money to have products on an eye-level place on the shelf.


Or, Walmart can pivot to entirely online delivery shopping and save loads of money by not having stores.

Or, Amazon can slide into the groceries space.
