How did most people pay for things through out the 1920?

During the 1920s, most people primarily paid for goods and services using cash, as credit cards had not yet been introduced. Many consumers also relied on installment plans, allowing them to make smaller payments over time for larger purchases, such as cars and household appliances. Additionally, bartering and checks were common, especially in rural areas. The decade saw a rise in consumerism, leading to an increased reliance on these payment methods.
