Sales taxes in the US are truly and insanely decentralized. The US has thousands of independent sales tax authorities with their own laws and regulations about how sales tax must be computed and displayed. These jurisdictions overlap, the sales tax you pay may be the aggregate of multiple different sales tax authorities between which there is no coordination.

I'm all for eliminating the penny and rounding to the nearest 5 cents or whatever. But I am not so callous as to ignore the reality that doing this de facto forces many businesses to break the law because compliance is impossible for reasons completely outside their control.
Maybe you're cool with breaking some eggs to make an omelette but I find it pretty gross and immoral to dictate change without satisfying the preconditions that allow it to occur legally for everyone involved.
