A Cashback Bonus is a type of promotion offered by online casinos, or other websites and services, to their customers where they get to take advantage of a refund on certain deposits or profits they make from gambling activities. It works the same way as a discount on a purchase, but with the exception that the customer receives a portion of the amount they have gambled as an immediate bonus. This type of reward helps to make up for some of the losses experienced by the gambler and also adds real money to their account, allowing them to play longer with the same bankroll.
