"it doesn't look like there is anything "odd" going on in regard to the Lapsang Souchong. It is still widely available all over the internet at some large recognizable tea sellers."
That is precisely what is "odd" - if not for internet commerce, a relatively new development, this tea would now be unavailable, when up to a few years ago, I could buy it without a credit card or an internet connection. I could buy it for home, I could buy it at a local tea room (since closed).
Maybe it is my age, but it does seem odd to me that I would have to mail-order a "staple", that in essence, I have to register with a seller in order to obtain a couple of ounces of tea.
Nice of you to take the time to look into this.
