Dont't give discount to reduced priced products to groups with discount

[Budapestis]

Hello!

 

I have a problem. I've created a group on my shop for bigger customers with 16% discount.

My problem is, that I have products with reduced price, and they get 16% even from the reduced prices, and that's what I don't want. I just want them to get 16% on every products which are not on sale and get the same reduced price as everyone on the reduced priced products.

 

Is it possible?

I'm using prestashop 1.5.

 

Sorry if it sounds complicated, I'm not very good at english

 

Thanks for the help!
