MakeThisButtonMoreExpensive

Make This Button More Expensive is a public internet experiment with one simple rule: every completed purchase makes the button exactly $1 more expensive for the next person.

Each buyer gets a permanent public receipt with their name and message, and the history never resets.

It starts as a joke, but there’s also a real advertising angle. If the site gets attention, early buyers end up with very cheap permanent placement in a public history that gets more expensive over time.
