I treat myself to a few quarter-pound bags from Chicago's Rare Tea Cellar twice a year. I get a lot of loose-leaf teas as gifts, as well. My two "daily drinkers" are the Wagh Bakri Masala Chai which I get in a 100-bag box up on Devon Street (the Indian / Georgian neighborhood in Chicago); and a fujian tea that I identify by it's bright red box, which I get in either Chinatown or the Korean grocer nearer my house.
I'm also partial to Czar Nicholas ][, but I don't make a point of always having some on hand.
