Inventory device for packaged items

The inventory device comprises a shelf adapted to support a plurality of rows of packaged items, each row extending from front to rear of the shelf, upstanding pins on the front of the shelf approximately centered before each row, each pin being adapted to receive a sales slip for each item sold, so that when an item is removed the total of the remaining items in the row and the sales slips on the pin associated with that row should equal the original total number of items and thus provides a ready indication of theft by sales personnel, or others.
