Discount by weight

[Lars47]

Hi.

 

Is it possible to make a discount based on the total weight of some of the goods in the cart.

 

example:

I sell beef in packages of 2 kg.

Pork in packages of 1 kg.

And I also sell computers (just an example .

 

If a customer buy both meat and the computer, then the discount shall only apply on the meat and not the computer. The discount shall apply on the meat when the cart contains a total of 10 kg meat = 5 % discount, 20 kg = 10 % discount and 30 kg = 15 % discount.

 

Thank you.

Lars.
