Explain in detail

One of the most expensive coffee in the world?! Would you be willing to pay $20 for a cup of this coffee? If so, how much is your consumer surplus in this transaction? How much are you willing to pay for a cup of exotic coffee and then brag to your friends and family? So if we put it that way, this coffee is really not that so expensive. I haven't seen it in Houston yet, but you can buy it on Amazon
