How did people buy products in the 1920s?

In the 1920s, people primarily bought products through department stores and local shops, which were popular for their wide selection and convenience. Mail-order catalogs, such as those from Sears and Roebuck, also gained popularity, allowing consumers in rural areas to purchase items from the comfort of their homes. Additionally, the rise of consumer credit, including installment plans, enabled more people to afford larger purchases. The decade marked a shift towards a consumer-oriented society, fueled by economic growth and innovative marketing.
