Walmart just built a giant vending machine for groceries

Walmart is trying to make it easier to pick up online grocery orders.

The retailer is testing a giant self-service kiosk in the parking lot of a supercenter in Warr Acres, Oklahoma, where customers can pick up online grocery orders without interacting with employees.

Customers purchase and pay for groceries online, then Walmart employees pick and pack their orders and store them in bins in the 20-foot-by-80-foot kiosk.

The kiosk has refrigerators and freezers inside that keep the groceries fresh.

When customers arrive to pick up their orders, they walk up to the kiosk and type in a code and their groceries appear within a minute.
