more on shipping

I just got in some 5-inch cube boxes that I can squeeze about 72 disks into. My cost of shipping that to Australia, New Zealand, the UK and EU countries is about $37. Cost of shipping to Canada is about $27. But here's the catch: customs. I can't put actual value on the customs form unless you want to pay a duty on the package. I don't mind that, but if the box disappears en route I'm not going to take the hit. Nearly $350. You see, there's always a catch. I receive complaints on the shipping, especially from Australia, from people claiming I can ship dozens of disks for not much more. True, but who is accepting responsibility for the package arriving? Not me.
