I am looking for something that can give my online store a referral program to earn points and use those points to redeem custom rewards.
Really hope something like this exists, any help is much appreciated
Quite a lot of Apps offer loyalty program and rewards customers credits in your store. Typically, a customer will receive an email with a referral code which they can buy next items cheaper if that customer refers another customers.

Hope this helps!
