What is the difference between Sale Discounts and Buyer Loyalty Discounts?

Buyer engagement program is a continuous process allowing buyers to purchase models with credits collected and rewards loyal returning customers. Sales, on the other hand, happen rarely - on specific occasions like Black Friday, Christmas, or a few campaigns planned by our marketing team. Both programs cap discounts - Sale Discounts to 50% and Buyer Loyalty Discounts to 30% at the maximum. These discounts are never summed.
