I've seen them at all the Williams Sonoma stores a while ago. I'm to sure if they still carry them. Also, believe it or not, I found them at Uwajimaya in Beaverton of all places, a couple of years back. Uwajimaya even had flavours that WS didn't carry, such as the Pomegranate Oolong. I haven't been back to Uwajimaya looking for them so I'm not sure if they still carry them. But if you were in the area, it might be worth a look.
