I'm going to take a wild guess and say that you may be able to ship wine to Washington state, but not liquor. Since Washington seems to have state stores, you're pretty stuck. However, they have a pretty cool website and you can find anything on it as well as which stores in the state have things, as well as how much they have in stock. The do have the Dalmore Cigar and Balvenie Doublewood listed, BTW.
