> But that's already the case today. I see the price per item, not counting any potential bulk rebates or optional coupon codes, as it's not a priori clear what else I'll buy. On the other hand, sales tax can always be calculated per item sold, as far as I know. That’s fair. I guess I just don’t see the value in displaying the per-item tax when there’s still a bunch of other unknowable charges. But I agree, as far as I understand it would be possible to show the per-item price with sales tax. But my experience with tax is that it’s always more complicated than you expect, even when you think it’s more complicated than you expect.
