You can purchase the card at any of the VVV tourist offices (located in Schipol airport, Amsterdam Centraal Station, Leidesplein, and a few other places) for: Junior Card (up to age 24) NLG 25 Adult Card (from age 25 to 54 inclusive) NLG 55 Senior Card (from age 55) NLG 45

It's a great price if you plan on going to two or more museums. Admissions to the Rijksmuseum is about NLG 26 and the Van Gogh Museum is around the same. A friend who came to visit me recently had to pay twice for the Van Gogh museum. We left at closing time and she did not have a chance to go to the museum bookstore. She went back the next day just to go to the shop, but still had to pay full admission again!
