Good afternoon,

I am having a project but I got stuck...
basically, the company has different material in different warehouses, and we want to ship, for example, three different material, but they are in different warehouses, and different warehouses have the different weight limit, and different weight limit has different shipping line options. so we wanted to figure out the most cost effective way to ship the material. and I searched online, and I only found very simple project on youtube.
So I was wondering if anyone has some kind of tutorial for me to look up?
