Is it possible to discount a fixed amount based on the weight of the total ordered items?
I have a store which sells fruits. Let's suppose fruit is available in different modifier_options
Oranges --product 1 kg basket --modifier (2$ per kg.) 2 kg bag --modifier (1.90$ per kg.) 4 kg barrell --modifier (1.50$ per kg.)
Eg: The customer orders 1 basket and 2 bags, for a total of 5kg. (no discount) The customer orders 2 baskets and 2 bags, for a total of 6kg. (1$ discount) Same applies if: The customer orders 1 barrell and 2 bags, for a total of 6kg. (1$ discount)
