I smell....I smell....SPAM!!
You are right! There is no such online tea store which provides online puerh tea learning courses. I am excited that this store offers something like that.
Here is the puerh tea discussion group where people talk about anything related to tea. Hobbes was so zealous about EoT a few years back, Shah8 talked about SampleTeas, and others other tea stores and their teas. We all spam each other and we enjoy it because we love drinking puerh and talking about it. Honestly, without all these spams, I would have never heard of EoT, SampleTeas and others. So you have come to the right place to enjoy being spammed and spamming others.
