Shadovved - maybe this has been covered before but for the next GB you run can you add a faster shipping option? I realize it would be more expensive.
Registered mail is essentially USPS Priority and normal is USPS First Class, both will be processed at around the same time by your post office and customs.
So I doubt it makes any difference if I go for something faster but still via the standard postal system since it's the customs & PO that are causing the bottleneck.
Usually packages arrive in the destination country 2-3 working days after I post it, so it's really not whether the shipping is fast or slow but the customs process holding up everything.
However, if you decide to use something non-standard, I have FedEx available at $50.....probably will be faster but will it be worth it?
