Ah, all these teas! I could spend here hours! No kidding. I have been such a tea addict after I discovered David's Teas, but then moved to US where they did not have my favorite tea shop. Slowly, I got used to Teavana Teas, although I was (and still am) disappointed that customers have to buy the minimum of 2 oz. of tea, no less. (At David's Tea you can buy any amount, even just for 2 cups!) and pay only few dollars. So I consider Teavana teas more expensive - I must buy at least 50g and pay about $10.00. And if I don't like the tea - my bad. Of course, you can try the tea first but many teas cost $5.60 just for a cup!
However, not looking at the prices, I still prefer David's Teas over Teavana just because most Teavana Teas are way too flavorful - just way too much fruit, chocolate chips, spices, etc.
