Not sure how the prices compare on teas, I`ve never shopped these, but, I have purchased from this company. . .www.atlanticspice.com
Also, you have probably already done this, but I went to google and typed in the following in the search bar and a ton of placing selling loose leaf teas and accessories in bulk, and/or, at wholesale, popped up:
loose leaf tea and accessories, wholesale, bulk
Hope this helps.
