The promo code says ‘Get 20% Off’, but I only got RM10 off. Why is that?

Some promo codes have a maximum discount value that will be clearly written under the promo code banner / terms & conditions. It means that the highest discount amount will only be RM10.

For example, if you apply the ‘Get 20% Off, with a maximum discount value of RM10' promo code to a purchase of RM100, you will only receive RM10 off your purchase.
