Editing Loyalty program (section)

===Tiers===
Programs with tiers define levels (such as silver, gold, and platinum levels) that customers are upgraded to when they spend enough with the merchant(s), usually over a certain period of time such as a year. For example, Sephora gives 1 point for $1 spent. Once customers earn a specific number of points, they can enter a new level with higher discounts and exclusive products.
