Why do you keep saying "thousands"? Most counties, and cities have the same sales tax as their state.
Absolutely not. Most states have a rate, but then every single jurisdiction in that state can tack on additional rates. Further, it's not just a rate, it also depends on what products. For example, selling eggs in one state is exempt from sales tax, in another it's not, and in another it's only in a pack of a dozen.
The states are trying to force their logistics problem to be a problem for the vendors.
