Is it mandatory for all products to participate in the Jarmaq loyalty program?

No, participation of products in the loyalty program is entirely voluntary. The seller independently decides which specific items are eligible for payment with points and which are not. In each product's listing in the Atasuai Seller dashboard, you can choose one of the fixed discount levels: 0%, 5%, 10%, or 20%. If you set 0%, the item is sold at full price without any deduction of the buyer's points.
