Let me know if you do find one from target. As tea drinking becomes more popular in the united state im sure there will be more and more options as the years go by!
I think where disrespect comes into play is when someone tries to pass themselves off as something they are not, which I hope I have not done. I only spent one day in Japan on my way to china (and drank tea out of a can). But I think people can enjoy matcha without doing the ceremony. I sell most of my matcha to people who just want more caffeine. Many of them just shake it up in a water bottle with cold water.
Thanks for the video suggestion!
