In California there are so many different sales taxes. The state gets the biggest cut, but there are regional, county, and city taxes, with slightly different rates depending on which city/county. We get temporary statewide taxes, like some implemented after disasters. The BART (transit) sales tax in the San Francisco Bay Area has been around since I was a kid. I do remember when I bought a car, the sales tax corresponded to where I lived. Something about preventing shopping around for the lowest sales tax on a big ticket item.
I still haven't figured out all the "food items" that are are taxable in California. Anything carbonated is. Hot foods/beverages are supposed to be except maybe coffee? A whole pie isn't taxable if ordered to go, but they can't provide forks. I get the feeling that a lot of businesses treat the same items differently. One of the weird things is prescription items aren't taxable.
It's got to be weird living near a border, like between Portland, Oregon and Vancouver, Washington. Oregonians can supposedly buy things in Washington and flash their Oregon ID to avoid paying sales taxes, but only if it's going to be taken back to Oregon. People cross into Oregon to buy stuff and don't pay "use tax" when getting home.
