Hi does anyone know the cheapest way to send luggage, books, etc back to their own countries?

China Post by ship takes three months, but is considered a bit cheaper. How much does that cost?

Does anyone have any other suggestions? Please email me at tanny.por@gmail.com if you know, thanks!

you can check with an air cargo agent. it's resonably cheap. depending on the country, you can check with Thai airways cargo or any chinese carriers. good luck!
