Samsung Rewards Points are calculated based on the order subtotal (excluding taxes and shipping, promotional payment methods, as well as any excluded items/products).

For example, if you spend 1000 SAR and pay 500 SAR with a credit card, and 500 SAR in Rewards, you will earn up to 3% in Rewards on the 500 SAR paid with the credit card (15 SAR = 5 P)
