Persactly, and you would think they would have learned their lesson with the "scan and go" program. Hell, for a few months you could pick up a scanner at the front, scan your items as you shopped, and then check out at the front and leave.
Shrink exploded from the getgo. And the program was eliminated within a few months as store after store had terrible inventories. Not like you couldn't see it coming within the first two weeks.
Walmart utilizes a perpetual inventory and an automated replenishment system. When items come in, they are added to the inventory, when they are scanned at the checkout, they are taken off the inventory. When the inventory gets to the reorder point, it is automatically ordered.
Now, Walmart sells ground chuck rolls. One pound, three pound, and five pound rolls. Within two weeks, the five pound rolls were empty in the shelf while there would be multiple cases of one pound rolls in the back. The perpetual inventory would be off by dozens of rolls. Comical when you think about. Customers would scan the one pound roll, take the five pound roll. And this didn't happen a few times a week, it happened dozens of times a week.
The solution is so damn simple, and really inexpensive. RFID tags. Linked credit cards or bank accounts. Come on in, take what you want, put in your buggy or shove it up your ass, doesn't matter. When you walk out the door your bank account is automatically charged. Amazon has been doing it for a couple of years in select locations.
