Nobody sends a press release about a price
A company will write a blog post about a new feature and say nothing at all about the tier it quietly added underneath. The pricing page is the only place it exists, and it changes without a version number, a date or a note.
That is not deception. It is just that a pricing page is a product surface, not a communication. It gets edited the way a button gets edited.
The old version is the whole trick
Catching the change requires having the previous version. Not a memory of it, not a screenshot someone took — the actual earlier value, held next to the new one, so the size of the move is exact rather than remembered.
Every row on Changes carries its own before and after, and its own window. They are not all seven days long: some sources run weekly, some every four weeks, and a row that says otherwise would be a rounder story than the truth.
The useful question is what it opens
A rival adding a cheaper rung is not interesting on its own. It is interesting because it tells you where the price-sensitive buyer now has somewhere to land, and whether you have anywhere to send them.
That is the difference between a monitoring tool and a brief. The number is the start of the sentence, not the end of it.
