I spent this week telling people to put it on their pricing page, next to the price. Three separate founders pushed back with the same worry: if they can negotiate, why would anyone pay list price?

They were right about the placement. The link works best where you're already losing the person: the end of a trial, the cancellation flow, a quote that went quiet, etc. On the pricing page it only makes sense when you were going to discount anyway, Black Friday style.
