using quantity discount module for 3x2 Promotion

[minotaurus]

Hi everyone

Lets say a customer adds 3 products

item A --- 20$
Item B --- 30$
Item C --- 40$

I would like to offer a 3x2 promotion ( cheaper products is for free )

I'm using quantity discount in this way

if there is more than 2 products, apply 30% discount,

but it doesn't do EXACTLY what I need,

In my example , the idea is that the user gets item A for free ( discount of -20$ )

but the calculation does this: DIscount = ((20+30+40)*30)/100

Wich is 27$

Can you help me to get the results I need ( with this or other order total module )?

Thanks a lot
