Walmart isn't letting up in its quest to one-up Amazon whenever possible, especially when it comes to in-person pickups. The retailer is testing a kiosk in Oklahoma City that lets you pick up your online groceries at any time of the day or week. Instead of parking and waiting for a staffer to bring out your food, you enter a pickup code and wait for the kiosk to automatically fetch the order from bins inside. You need to spend at least $30 and order during store hours, but there are no special fees or other limitations. If you can't fetch your groceries until 3AM on Sunday, you're fine.
