Blue Chip Stamps started as a trading stamps company called "Blue Chip Stamp Company." They were a competitor of S&H Green Stamps. Blue Chip stamps were a loyalty program for customers, similar to discount cards issued by pharmacies and grocery stores in the digital era. A customer making a purchase at a participating store would be given stamps in proportion to the dollar amount of the purchase. The stamps were dispensed by machines adjacent to the cash register. The customer would paste the stamps into books. The books could then be taken to a redemption center and redeemed for merchandise, such as lawn furniture, dining tables, tableware, and many other items. The redemption centers did not maintain a full inventory of items but would order from a catalog on behalf of the customer.
