You raise good points. The expensive part for me was the discovery aspect. Once you know what you like it’s not bad but the learning part…trying all the different greens and oolongs and pu’er and black teas - that was a little nuts at the beginning.
Now I have about 10 varieties that I like for different occasions and I stick to those and it’s not too bad.
Biggest splurge for me was an ember mug. Im a little embarrassed by how expensive it was, but honestly no regrets. Perfect temp tea for hours.
