I sent my wife up to the store on 4th, and found that it was well worth the trip from Phoenix. (there was something about a family christening going on there too, in seattle... not at WSLCB) The nice thing about washington state stores is that they list their inventories (more or less) online,

along with the manager's phone number to check on stock. While I am not a big fan of state level regulation of liquor, it does cut down on hunting time (and I suppose the fun) of finding bottles not readily available in your area.
