this is something incredible.
there is a product, the price is 10. there is a 10% discount in it (for everyone)
there is a rule (for everyone). if the order is more than 50, then a 20% discount.
This means, when ordering 10 pieces, the total cost should be 80.
but the program does 2 discounts. first 10% and then another 20%
how to make only one discount apply?
