Reward system is a good way to encourage customers to come back and buy more. We understand that acquiring new customers can be very difficult and expensive. It maybe easier to increase sales by focusing on building strong relationship with your current customers to drive repetitive purchases.
The reward system runs itself without human intervention. Keeps your customers around longer and spending more without extra work.
After a user bought his first product, when he/she checkout another product he/she will be asked to redeem the wallet.
The user can save all his/her reward and use it later.
