Buying lot of green tea is unadvisable, mostly because the tea itself
will deteriorate over the time.
Also, this post looks like an awkward advertisement.

All right, Tomas, what have you to suggest instead of what I "advertise"?
My guess is that you are biased against buying "lot of green tea," but is
2 lbs. really a lot? If it's as palatable as I expect, it'll be gone in
a year. Ordering less more often does increase shipping and handling
cost, you know. bookburn


Bookburn, I drink Chinese and Japanese green tea in the spring. Usually, I do not have any left by the middle of summer. After several weeks, I note that the freshness I like so much in a green tea is mostly gone. That's my experience. Two pounds is a tremendous amount of tea, for me and I suspect for most of us. Buying that much green tea at a time would be foolish for me, although, if you can't taste the difference between that tea when you first open it and that tea a year later, no harm done.
