When I first located this tea, it was priced under $4 for 6 ounces; the price has gone up to about $5, but this still makes it extraordinarily cheap as green teas go. What is most surprising about this tea, however, is how good it is.
Starway's products are not labelled with any brand name--Starway is just the name of the importer. Look for the green tins pictured below. As a side note, while I love this company's green and white teas, I do not recommend their oolong or Pu-erh (which come in brown tins).
Where to buy? Look in Asian markets, especially Chinese ones. I have found this tea for sale in Chinese and Vietnamese markets in Philadelphia, but have never seen it for sale in Japanese or Korean markets, which tend to sell more Japanese-style green teas.
Warning: Although I also love the Huangshan Mao Feng green tea from this company, and have heard good things about their shou mei white tea, I do not recommend their oolongs or plain green tea.
