Hey Danny, try
Upton Tea.
Their stuff is amazing, they personalize the cans, and the selection is incredible.
Todd (RevSmoke) turned me on to the place. I've ordered 4 or 5 times and can't fault them on a thing.
They have $1.00 samplers for everything they offer, so you can try anything.
I don't know what has caffeine and what doesn't, but we go through tons of Mango Indica here.
They have a huge selection of every kind of tea. You'd have to find something you like. The prices are very fair and the quality of the teas are impeccable.
