Love that tin, Stitchawl! Very pretty. I do know that Lipton's teas are different in different countries, different varieties available, too. (Wow that's a lot of different in one sentence...).
I found Ahmad's at Amazon for what I would consider very reasonable prices. They seem to like to sell it in bulk, though.
