It works ok-ish. It works significantly better in almost every other country in the world. Yay for status quo bias! > You know where you live, you know what your local sales tax is. No, I in fact don't know, because I have better things to do than to keep up with what my city and state have extended sales tax to this month, what carveouts exist ("no sales tax on unhealthy snacks except ice cream" and stuff like that) etc. And there is absolutely no excuse for in-person stores that do, in fact, have perfect a priori knowledge of all of this.
