Wal-Mart recently discontinued locking only the Black hair care products in their cosmetics section.
My younger brother worked for Home Depot years ago. He told me that he was called into 'the office' and informed that he was catching to many people stealing. They told him that they already knew how much was being stolen and that the cost of those losses were already included in the prices of the products on the shelves.
They told him, let them have it.
