I call those asshole user stories unless there is a logged story “as a user, I expect inventory prices to be accurate in real time.”

I don’t like user stories that are anti-customer and in the developer’s favor unless it’s clear that there’s a path to fairness.

The motivation to a system should be to have as current as possible pricing, not some nightly batch that shows cheaper, unavailable prices and pisses off people when the real price is actually checked.
