Retailers locking up products to curb shoplifters

Retailers like Target, Walmart, Dollar General and Home Depot have talked about missing inventory more this past quarter than any quarter on record, according to data compiled by Bloomberg.

Retailers are concerned about a loss of profits because of shrinkage – an industry term that refers to the difference between the inventory a store has on its balance sheet and its actual inventory.   

To combat shoplifting, retailers are introducing strategies such as shorter store hours, self-servicing locking cabinets or smart shopping carts.
