After a lot of shopping around, I've found that The Headshop has the best prices on mushrooms, especially for the Copelanida Cyanescens (Hawaiian) variety. As of June 2007, 12g were 15 euros. Elsewhere, I could only find 10g packages and they cost anywhere from 15-19 euros. The guy who works there is very helpful and really knows his mushrooms.
