Discount order

[actualweb]

Hi,

 

I've got a product with a price of $11,55. There is an offer that makes it worth $9,7

And my customer group (id_group = 8) has a 15% of discount over the products.

 

The price I should get is:

- $9.7 - 15% = 8.25

 

But it seems prestashop if applying the 15% to 11.55 instead of the offer price.

 

I created a line in ps_specific_price which applies to all groups and the price is 11.55, the amount is 1.85 and the type is reduction, but it seems prestashop overrides this price for the customers group discount.

 

Any idea on how to configure it so the group discount is applied to the offer price instead of the product direct price?
