Ok so I have on my registration page where a person will enter billing information and then another section to enter student information, since the items they are buy will go to a student. Right now, since I have free shipping module install and all products are free shipping - it automatically fills the shipping information in with the billing address. What I need to do is pull the student information from the database and insert that into the shipping address instead of the billing address. I am assuming the shipping address gets pulled from the address_book table but I have not been able to figure out in what file this shipping information gets pulled from the database in....does anyone know what file(s) this takes place in?
