It's not great!
I am based in Bangkok and need to send one of my B&Rs to be fixed. They wrote to me and suggested I send it to UK or USA. The cost was prohibitive.
But I am going to US soon so will take it and courier it to them once in US. They told me they will cover the shipping charge to return it back to me in Bangkok (but won't cover the outward shipping charge).
Basically outside UK and USA, the outward shipping charge can be prohibitive.
