Big fan of Adagio
Big fan of Adagio! Their tea selection is expansive, their prices are reasonable, they let you make custom blends (or buy custom blends other users have made), they often include free goodies, and their rewards program is great. The only feature I've had mixed success with is their sample trading cards. It's an awesome feature in theory, letting you claim a free random sample "card" every week & trade said samples with other users or redeem them when you check out. In practice, I've had many cards for 6+ months that can't be redeemed and just say "Available Soon", and when I reached out to customer service to ask if there was an ETA for them they seemed to not know how the feature worked at all and couldn't help. So if you use the cards be prepared to wait a long time for some of them, maybe forever LOL. But aside from that it's a great site with great service!
