The first case is bizarre to me, unless that's a typo

> Bizarre

They just round more than you: I think your presumption that others should think like you is bizarre. Some people only round to 10 cents. If you are wealthy enough, you could easily round 10.99 to $0.

> I think your presumption that others should think like you is bizarre.

What I actually wrote was "bizarre to me", not just "bizarre" (as in your quote), so I don't think it's fair to say that my comment conveyed such presumption

I think it just proves that x.99 pricing works. It tripped up the poster who was trying to claim they mentally round up.

Which poster was claiming that?

No it's not, 10.99 for some reason works for me
