promise to pay only a sale price.

pay only a discount price.

The correct answer is promise to pay for goods later.

Buying on credit became especially popular in America during the 1920's. This ability to pay for goods over an extended period of time rather than paying for goods all at once appealed to many American citizens. This allowed many citizens the opportunity to buy luxury goods that they could not afford before this method of payment was invented.

However, this payment method is going to be one of the biggest factors in causing the Great Depression of the 1930's.
