I've been building a browser extension called Curb Your Consumerism that detects when you're on a checkout page for a website and redirects you to a screen that shows you how long you had to work to earn the purchase you're about to make. The idea is to get people to more consciously consume and in general reduce their consumption.
It's currently working, but I've stalled a bit because I'm not sure of the best way to promote it. ProductHunt is probably a good first step, but other suggestions welcome.
