Ok but what you're describing is the classic "be cheaper than competition, gain market share, then raise prices" and is basically how business works. Almost every company does this if they are run well enough to manage to pull it off. Setting up rules to trick customers to make mistakes and then demand 60 euros for printing a sheet of paper is morally dishonest and I would say most don't do this.
