This link was mentioned to my by drmcboy, plus I had stumbled on it a couple times. Delicious. Over xmas I ordered the Kona which is fucking amazing, and the fire starter blend which is very good if you like dark subtle flavors (like stouts). I just opened the Australian today and it's yummy. I get giddy everytime I take a sip.
Tea:
I like black tea. I don't care for green and can't stand herbal. Most green tea tastes like grass, most herbal tea (apart from being non-caffinated) tastes like cat pee strained through a sweaty sock.
Barry's. The only thing people drink in Ireland:

Stash. Based in Portland. The best bagged tea I've had.
Their white tea is easily the best white I've had (better for you than green).

Twinnings. More common in the midwest than stash. The 'Prince of Wales' is phenomenal.

Also there is Boston Harbor by the Davidson Newmon company. It's the oldest tea company in Britain and the same company that made the tea that was thrown in boston harbor.
