Rogue is one of the more expensive micros in Montana as well...although it isn't as bad as $15 a sixer for Dead Guy....it is around $10.
I have seen their 22 oz. bottles for around $15, though....some of their bigger offerings. Too pricey for me.
I really don't buy much bottled micros, though....thats what homebrew is for! My intake of micros is usually limited to a couple of pints at the tavern.
