Do you have any ethnic stores around, especially Middle Eastern? They carry delicious loose teas, usually the Ahmad brand. My favorite is the black tea with cardamon.
Asian stores will carry very nice Green teas and Oolong loose leaf teas. Choose a young or spring leaf for the green tea to make a soft, aromatic and pleasant tea. Older green teas are bitter. I usually just use Costco's green tea...it's the best on the market for the price.
Also, check out a Teaopia store if you have on in a mall.
And, stop by any good local coffee shop. Most carry loose leaf teas. Even their bagged ones are good, like Numi.
