It's very frustrating trying to calculate the transit time on fedex.

I would like to calculate the time it would take to send a package from Hong Kong, China to Philadelphia, USA - However fedex.com asks for a zip code for the chinese export address, but there is no zip code for Hong Kong. so how in the earth are you supposed to calculate shipping to/from Hong Kong??!

It asks for a zip code, if you put nothing it tells you to do it again, if you put 852, it tells you to do it again, if you put HONG KONG or HK or anything remotely related to Hong Kong it tells you to do it again, it is driving me crazy I think I need therapy..
