I go through a ton of this stuff--have fun!
In Portland Micucci has it, as does Rosemont on Brighton (I'm not sure about the other Rosemont locations tho--); and Whole Foods often, but not always, has the King Arthur Italian-Style in stock--an American clone of the Italian 00, which is quite nice, as well.
Thanks for the feedback.
Tried Rosemont on Brighton today and they didn't have it and said they don't ever carry it (not sure when you last bought it there and not sure if the clerk helping me really knew). Called the other Rosemont store in Portland and they also said they don't carry it. Being Sunday, Micucci was closed so couldn't go there. Since the SO wanted homemade pizza still, we went to Whole Foods and thankfully they had the Italian-style King Arthur.
Thanks again for the help. We will give the KA flour a try.
