Starbucks serves Tazo Chai (liquid in a box form). IMNSHO the yummiest chai teas on the market are Oregon Chai (liquid, mix it with milk) and Good Earth's Vanilla Chai (tea bags). Besides of course the chai or yogi tea you can get at an indian restaurant which are usually superior (but not always, sniff.)
Chai usually contains: black pepper, cardamom, clove, ginger, cinnamon, black tea and is mixed with milk and sugar or honey. So Bengal and Plunder both sound like they would be close!!
sometimes chai contains star anise. The "kashmiri chai" by Oregon Chai has almond in it (and is a green tea, not a black tea) but that is somewhat unusual. I don't think I've ever seen a chai with orange peel.
Pike Place Market Spice has orange peel and cinnamon, and is very good. Good Earth's signature blend is also an orange peel and spice. Yum. Neither are chai, but they are tasty tea.
Lush's "Chai" doesn't smell at all like Chai to me. I gave away the bottle I got in September to a male friend. I'm fairly picky about my chai scents, I'm a freak.
I made a super wonderful batch of chai tea soap but I think I'm out (except for my personal stash.)
