I find teavana to be hideously overpriced, but I am happy that I can get a good cup of tea to go at malls now.
My hands down favourite loose leaf tea is Russian Earl Grey from The Metropolitan Tea Company. It's a bit of a citrusy twist on Earl Grey. The tea/coffee shop in Eau Claire sells Metropolitan teas, but I don't know if they carry this one - I get it by the 1 kg package at Glenn's in Red Deer.
MRC - I've had the grape flavoured white tea from Naked Leaf - it is very good.
