I bought a 50lb bag of KASL from them yesterday. They also have Caputo and Guisto and others. As mentioned in another thread, very easy to deal with. Just call ahead for an order, then go to the door and knock (bell is broken), do the paperwork and pay, then pick it up at the loading dock. $28 for a 50lb bag of KASL. Not too bad. It would have been almost that much for a 3lb bag with S&H from King Arthur to my door.
I'm splitting the bag with a couple others. No way I could use 50 lbs in a reasonable amount of time. Besides, I'm making my wife tired of eating my pizzas.
