M N asked:
How can I ship some of my belonging to my home town?
I am possibly returning oversea and I needed to ship some of the staffs in order to keep some of my belonging that I used in here.
Since I will not able to take all of my staff to the airport since there is limitation for the amount of luggage that I can bring, I am assuming one to check-in and one small one on borad. Which make it two.
I wanted to know what is the affordable shipping method shipping from NY to Tokyo

It is spelled stuff, not staff.
You can send DHL. Try calling LBC or Alpha Cargo if they shipped to Tokyo. I used it to shipped things to my country. It is a fixed price around 85-90 dollars depending on the location. But there is no limit to the weight. If you are packing breakables, make sure you packed them with lots of protection (towels, clothes).
Believe it or not USPS
