What really makes sales taxes fun in the US is that they are variable in many states. If I go to my local Walmart at the start of the school year, some items I pick up may be tax-free because they are considered school supplies and there's a "sales tax holiday", others items are considered "Groceries" and will be taxed at a reduced rate, but prepared (hot) foods, booze, and non-food items are taxed at the full rate. Then there are the cities and counties that have additional sales taxes. When I lived in Germany it took me about 5 minutes to fall in love with prices being listed inclusive of taxes.
