This could be a good idea if you are a trusting person. Walmart is testing out a new service in three different cities where they will not only deliver your groceries, but a trusted driver will PUT THEM AWAY IN YOUR FRIDGE! Employees must pass a background check, work for the company at least a year, pass a special driving test, and will live stream the video of the delivery so you can see them in your home. It will be a monthly service around $15 and a one time purchase of a special lock system (about $50). You won't need to change your locks, this will just adapt yours to a special key less system.
