>also interesting :) what i knew was that some or most states display the prices without tax, so you'll only know the total of your grocery trip at the checkout. It comes up on /r/askamericans all the time, but it's not realistic to include tax on the prices because there are so many different taxing zones. A large city may have multiple. Most places you can figure it's going to be ~10% and might be pleasantly surprised when it's less. Everyone knows to figure roughly 10% extra, so it's not a chore or anything, even children figure it out.
