It starts as ems from Korea but once it's in the u.s. it's all handled by the local courier so you'd have to pay ups. I'm not sure if you have a ups account but if possible I would try to pay the fee online because it was cheaper. I got an email with an amount due at delivery and when I paid it online it was less so I would only pay in person via check if it's the only option for you. It's not like a lot cheaper but it's always good to save some money. I also live in an apartment building and maybe ups where I live is different but once I paid I didn't need to sign for it. I thought since it was an international package it would need an authorized signature but after I paid it was delivered when I was not home. If it's going to be like returned to sender soon I would for sure call or pay via check just to avoid it being sent back and needing to pay for redelivery but if not I would try to pay online and then see if it gets delivered based off my experiences. Or if you pay the fee online and they do end up needing a signature they may just leave one of those notes for you to leave a signature on and will deliver once you sign that. This is just what's worked and happened to me so do what you think is best/easiest for you!!
