Cart Discount And Sale - Applying Only One Superior Discount.

[Jurist]

Hello.

 

Is it possible to set prestashop to apply only one discount? For eg, we have 20% sale for a products.

We give 10% cart discount for customerA and 30% for customerB. 

 

We would like to make our customerA to have product sale (20%) active, and make cart rule impossible to add, there should be only one, stronger sale active, 20%.

 

In case of customerB he should be able to add Cart Rule to reduce price by 30%, but after this, product sale should be removed.

 

I have edited CartRule.php to use solution from post #13 here:

 

https://www.prestashop.com/forums/topic/290274-disabling-discounts-cart-rules-to-items-already-on-sale/

 

and it's currently working that if there's already sale it's impossible to add cart rule, that's fine.

 

But what if cart rule is stronger than the current sale?

 

Kind regards
