I'm finishing a prestashop store but i need to add functionalities with a module.
The products are in the catalog as units, but i want to sell in different box quantities.
A product can only be sold in boxes of 6, 12 or 1000 units for example and can have one two, three or four colours.
The box units are different by product.
The box unit price is different by number of colours and quantity in box.
There is also a tax that should be charged in cart only once by ref. if a product with this characteristics is on it, that varies according to total units and number of colours.
I attach a picture of what should be on the product page. The box prices should be calculated and shown according to the # of colours chosen.
