Are All Prices Final

Hello, I’m wandering whether there is a setting that makes the customers suggested price not final.

As it seems if I have a product for ￡100 & one for ￡1 the buyer can purchase either immediately for ￡1. When I change minimum settings it then only allows customer to purchase for that minimum value whether ￡100 or ￡1.

Or is it only a plugin that makes customers pay what they want and not request a price
