A price list looks like arithmetic and behaves like copywriting. The number matters less than what sits beside it: what is included, what is named, what is conspicuously absent.
Chrientmip's first price list had five tiers, and almost every client picked the second one — not because it fit, but because five options is a decision and people avoid decisions. Cutting to three moved the average order up without touching a single number.
The fourth rewrite is the one still running. It stopped describing deliverables and started describing situations: the tier for a profile picture, the tier for a full reference sheet an artist will work from, the tier for commercial use. Clients stopped asking which one they needed.
