We have separated subscription discounts from standard order length discounts. They can be configured independently and work similarly but not identically - discounts are tied to specific subscription cycle ranges, not order day counts.

Three discount configuration types are available:

Fixed - the discount is applied from the very first subscription cycle, i.e. from the first order placed within the subscription.
Progressive - the discount increases over time; subsequent subscription cycles receive higher discounts.
Degressive - the discount decreases over time. The customer receives a high initial discount that gradually declines - it is also possible to completely remove the discount after a given cycle.

With each automatic subscription renewal, the system checks the customer's current subscription cycle and applies the appropriate discount.

When placing the first order, the discount can be combined with a promo code.
