Cashback is a term used in finance and marketing to refer to the practice of giving customers a portion of their money back after a purchase has been made. This can be done as a reward for shopping at certain stores, using specific credit cards or completing online purchases through cashback websites. The amount of cashback given varies depending on the promotion and is usually calculated as a percentage of the total purchase price. Cashback offers are often used by businesses to incentivize customers to make purchases they may not have otherwise made, or to reward loyal customers for their continued patronage.
