As a Dutchman I buy almost all in ........ Germany; with on-line Aurinum and Auragentum being cheaper than the largest Dutch online shop.
Aschhoff Edelmetalle has all Lunar series I II and III Some of the Dutch tradiotional gold selelrs are a real scamm. They just order in Germany themselves adn let you pay their margin. Ordering time therefore is 3 weeks!
