Thanks, I tried to register and it asked for certified document. Actually, I just wanted to see the shipping costs.
Yes, that's one of the things that puts many folk off, the documentation process.
The postage is very expensive, it's normally sent to the East coast via Toll Priority; the fee is about 17.50AUD per kilogram so, say you purchased 250 coins, you'd expect to pay about 135 - 140 bucks something like that and if you add insurance it's even more costly.
