Thinking of Amsterdam....

[psteve]

Amsterdam can be pricey and I prefer Den Hague for buying weed from.

I completely agree. My favorite deal in Holland is the Haze in Den Haag at coffeeshop 'The Crow', on Hooigracht. I also frequent 'the Juke Box', 'Happy Smile', 'Meneer Janssen', and 'Blue & White', in Scheveningen.
Other great towns for getting better deals include Utrecht, Delft, Nijmegen (I love 'de Kronkel'!), Den Bosch, and Haarlem.
Rotterdam is a great city for weed, but not necessarily cheap. Some of my favorite shops in R'dam are 'De Schurk', 'Sky High', and the now closed 'Sensi Cafe'.
