So do you think Teavana is worth the price? Their prices seem to run a little on the high side.[/QUOTE]Teavana is decent. Republic of Tea makes a good Chai.
For myself, no. I can get just as much Republic Tea as Teavana and it costs a little less. It really, REALLY, depends on taste.
Your best option is to get a small sampling and try it out. If you're ever at a store, they have teas you can test out and see if you think it's worth it. Like anything food wise, it's all about personal taste.
