There are pretty good discounts for using UPS 3 day expedited service.   An example is Germany:

2 pounds $32

3 pounds $48

4 pounds $54

5 pounds $58

6 pounds $60

7 pounds $62

8 pounds $66

If you email me what you want I can calculate rates.  Some areas will be cheaper and some more expensive.  Especially Japan and Australia and possible South America.
