Hi all,

I've been searching for an answer in the forum but I'm not capable of doing so. 

I'm selling scale modelling products in my website. Customers may purchase a single item or multiple items, of course, but when it comes to shipping prices, Odoo calculates the shipping based on the total adding of weights/volumes of all the items.

My question is: Is there a way in Odoo standalone or an external app to calculate shipping price depending on standard shipping box sizes?

Say I have 3 or 4 standard boxes for shipping. How can I make the selection of each box size  for the order, depending on the content?

I hope my question makes sense.

Thanks for your help!
