Costco's Kirkland brand green tea
You'll need to be a Costco member (or know one) to get this tea.
It currently sells for $12.99 for 100 bags.
If you're thinking "It's cheap, it must be crappy." Well, maybe in some cases, but not here. The taste is excellent, and the company that makes it is Ito-en, a Japanese beverage company. It's not green sawdust, it's a good mix of green tea. I was introduced to these by my Japanese coworkers at a company here in the US.
Two notes - first, strictly follow the instructions on the packet. 30 seconds in the cup is all you need. After that it can and will start to get bitter. Second, don't forget to tap out the loose green powder from the packet at the end. It adds to the flavor and adds more green tea to your cup - the stuff you're trying to get in you in the first place.
If you like green tea, give this a try. It's not much (13 cents a cup) and it's very, very good. If you've tried green tea and didn't like it, but feel the need to drink it anyway (for health, for fat loss, to impress your friends at the sushi bar), try to con a packet or two out of a friend and try it. It's better than most of the green teas I've tried that cost me much, much more.
