I agree with you on Upton's, too many choices and not enough focus.
They also have customer reviews on some teas, but none at all on many
others.
It seems like maybe they won't post reviews unless enough of them are
positive.
I did get a Ceylon from them that I liked. I intended to mix it with
the Assams but it is also good by itself.
I ordered three teas from TFactor today, hope they are good.
