Warehouse Clubs and Supermarket Loyalty Cards

Warehouse clubs and supermarket loyalty cards allow consumers to buy items at low prices that are unavailable to nonmembers. Warehouse clubs are large stores that offer a wide variety of products. They are able to offer low prices by selling bulk items and lowering overhead costs. The clubs require their customers to pay membership fees to shop there and take advantage of the savings they offer. Supermarket loyalty cards provide discounts to consumers and track their purchases so that retailers can collect data on customers’ shopping habits. Some people see this collection of personal data as an invasion of privacy. Most supermarket chains offer these cards, which are available for free.
