Specific price per lot

[Martin Uker K]

Hi,

 

I usually answer questions, but I'm having trouble with this one. The search is kind of hard since I'm not sure how this concept is called.

 

What I want :

 

1 product : 15 $

2 products : 20 $ (10$ each)

3 products : 35 $ (2 at 10, 1 at 15)

4 products : 40$

...

And so on. Basically, it's a typical "x for Z$" rule. In this case : 2 for 20. Specific price can do it in x and more. Which means : 3 would cost 30$ which goes against the business model.

 

Is there a way to create "2n" specific price rules? A module or anything?

 

Declinaison won't work, I alreayd have clothing using it for Color and size, I can't add a new attribute like "lot", and also it would disrupt the way the customer is using the application.

 

Pretty sure this is a concept that must have been asked before,

Many thanks to any hints or pointers,

 

Martin.
