Not sure if you know, but the Twinings website (
www.twinings.com) sells its tea at really reasonable prices ($2.99/box, $1.99/box for the tea of the month). If you sign up for email, they send a 20% off code every so often (or free shipping). I do large orders about 3 times per year.
My current bag favorites are the Christmas tea (tea of the month for December!) and the Apple Spice Chai. I get Lady Grey and Darjeeling loose leaf as well.
ETA: I have a tea kettle that I love! Like a PP, I will zap old tea in the microwave, but when I make it fresh it's in a tea kettle. In addition to the taste, the water doesn't seem to stay hot as long when it's been microwaved (but I notice that with food as well).
