I'd avoid buying tea from ebay or Amazon, especially when there are so independent dealers who will sell you tea that is reasonably priced, good quality and well sourced. I listed some on a previous post
I found them on Amazon at first, now I just go direct. SVTEA.Com. Simpson and Vail. I currently have 22 different teas in wine racks. the downside it that you have to order $50 to get free shipping, and if you don't they eat you up in shipping fees. what are you looking for? I have tried a LOT of the black teas, and can point you in the right direction
