Where does Tool prefer to sell their music?

They don't really have a website and the websites dedicated to the band don't sell their music. Obviously they don't sell through Apple and they don't allow streaming of their music. I can respect that, but I want to buy some damn albums. Do any of y'all know the preferred medium for purchasing Tool albums? I have a couple of vinyl records that happened to be in stock in Dallas, but I would like to get some CD's, and I guess if the band goes through so much trouble to make sure that their albums are purchased legally and under their control, I would like to get them through whatever method that may be.
