Cart rules and flash sales

[promod]

Hello

 

I'm using the cart rules for discount :

 

for 6 items : -10%

for 12 items : -15%

 

And I use the flash sale module like this:

product A : - 40% (available for 3 days)

 

When the customer add 1 product A in his cart it's the price is the basic price - 40% so it's ok.

 

But when he decides to change the quantity the price is changed like this :

from 6 items : basic price - 10%

from 12 items : basic price - 15%

 

But I need to apply -40% on all price (from 1 to 99999 items...)

 

It's seems that the cart rules is priority on the flash sale rules... But I need to do the inverse.

 

Someone can help me ?

 

Thanks
