Value is often discovered by asking what problem disappears after paying.

A good way to price something is to ask what stops being a problem after you pay. Sometimes the answer is specific and worth it, an hour returned, a worry removed, a task you genuinely cannot do. Sometimes there is no answer, and the purchase was about the moment of buying rather than anything afterward.

Use the question before your next non-trivial purchase. If you cannot name what disappears, that is usually the whole finding.
