Look for apple orchards and see if they sell it. I know Bellewood Acres in Bellingham sells straight cider, I think it's about $6 a gallon. Minea Farm in Redmond does too, but I've never been there. Their website mentions different flavors so it may be pre-spiced.
I'd check farmer's markets for Honey, I'm pretty sure that's where my BIL gets it for his mead, and it saves him quite a bit going straight to the beekeeper.
