Add different tiers to the loyalty program, ie. when customers spend a specific amount, they get rewarded with more points.

Have tiers where users who purchase continuously move up in tiers and gain incremental stages of discounts (limit after x tiers)

create several tiers of program members so if you earn a lot of points you become silver member or gold member and then each level comes with different perks

I'd like to be able to offer rewards to customers based on tiers (bronze $5 reward on birthday, silver $10 etc). I'd also like to be able to have a top tier for my VIP (reps) and have them have their own referral codes (turn off referral points in other tiers keep on in higher tiers) to earn points to avoid having multiple apps customers screens.
