Uwajimaya (if you're in the Seattle or Portland areas; they don't sell online, and their mail-order line is pretty limited) has plenty of imported teas. (Packaged before they're imported, that is.) Indian, Chinese, Japanese, probably Vietnamese and Indonesian I suppose, though I mostly stick to the Japanese ones there myself. Not the cheapest place for such stuff, but the most inclusive; a time-saver.
