I need some advice from anyone whos shipped from japanparts.com.

This is my first post, I have been around just reading posts for awhile and decided id finally make an account. I want to order a bodykit from there but I want to do it to seaport by sea cargo, but I havent seen any posts from anyone whos had this shipping option. I understand I have to wait an extra month, however its cheaper and I want to save some money. if anyone could please explain to me the process it'd be greatly appreciated, thank you very much!!

Edit: I live in new jersey
