My favourite ever teas are both from Teavana. I don't (as mentioned) drink bottled tea myself, but I drink hot tea very close to exclusively - generally if I'm not having alcohol I'm drinking tea.

The top one is their now discontinued Roze Marzipan tea. I've got a little of that left and have been rationing it to myself like my life depending on it.

Still available is their Almond Biscotti black tea. Milk and honey make this one just. Teagasm worthy.
