A trading stamp is a small paper stamp given to customers by retailers as part of a loyalty program 🪙. Customers collect these stamps and redeem them for merchandise or other rewards. They were popular in the mid-20th century as a way to encourage repeat business. Think of them as a precursor to modern-day reward points or cashback programs. Collecting trading stamps was a family activity, with everyone pitching in to fill stamp books. While less common now, they represent a piece of retail history.
