David Marks' website (http://www.djmarks.com) lists sources in their FAQ section. I would start there. He also sells a patination video which looks quite interesting as well.

Cheapchemicals.com is about $25 for 1 lb shipped (17 +8) but they have a $30 min order. 99.9% pure.
Ebay has a seller for about the same with no minimum buy. The David marks referred site shows only pre diluted stock and no price.

1 lb is alot since the mix is about 1tbs per 1cup water. As the shelf life is indefinate, 1lb could be handed down to your grandchildren with plenty to spare for their children.

The shelf life is indefinite. Storage is in sealed container in cool dry place. No mention of light but would assume store out of direct light also. US sales only and UPS ground only. Comes in sealed plastic bag in closed plastic screw on container.
