If you like a nice deep green tea, but want a really good bang for your buck, then try http://www.tealife.co.jp/drink/32.html which is what a lot of Japanese inns use. $15 for 100 5g tea bags (yes, it's not for purists). Grown in Japan and 95% as good as a much more expensive loose tea. 1 tea bag is good for about a litre of tea.
I've tried a lot of different brands and grades of tea, and while I can certainly appreciate the difference in some of the more expensive ones, I have not found any that are anywhere near the value proposition of this for a daily-drinking tea.
Unfortunately their FAQ shows that they don't ship outside of Japan.
You'd have to use a buying service like white rabbit express to act as a middleman, and though I don't know how much such services cost, would likely lower the value proposition.
