Well, I think consensus here is that the vast, vast majority of tea and
tea-related paraphenalia sold in the western hemisphere is vastly
overpriced.

So either your vendor is just pricing the stuff at a reasonable rate or it's
decidedly inferior.

For example, I see gaiwans sold online and in "occidental" stores (ie those
stores that sell oriental merchandise to a western market) for $30-50. But
I've found those same gaiwans on a site I mentioned a few weeks ago for
around $5. This at first seemed to me an incredible price, but talking to
people in the know has convinced me that this price is about average, and
about what you'd pay at a store in the East or catering to Easterners.

So if the tea comes and seems ok to you, it could be that you've just found
a store that isn't marking up its wares 5000%.
