But, what kind of software do they have that uses one price source for the unit pricing display and another source for calculating the total? It seems that it is destined to create more problems like this one.

POS software is right up there with vehicle infotainment systems when it comes to reliability and usability. They get the dregs of the programming world because decent coders have a way better selection of companies to work for.

Even when they get decent coders for the base code, feature creep eventually wrecks the system. I know someone who helped write the POS system used in Disney parks, and according to them the system they originally built didn't suck nearly as much as the system I used as a cast member, and it's the hastily tacked on bullshit (causing the initial competent team to quit) that ultimately broke it. That said, I do realize that most people will not admit to shipping shoddy code in the first place.

IDK, that seems like a really reasonable question tbh.

I imagine there's code to do something like currency conversion or maybe rewards points calculation so the displayed amount is not actually the number used for the final total

Deductions should also appear as a line item though.
