Honey is a program (they have a website and a Chrome extension you can use) that helps you find great deals and also earns you commission on purchases you make through it. It finds deals on Amazon, Groupon, Fandango, and other stores, and when you use the Find Savings or Activate options on those deals, you start earning HoneyGold (G). 1000G equals $10. You get to earn a randomized commission amount from your purchases made through the Honey program.
It runs in the background as you shop and tracks the purchases you make to calculate the HoneyGold earnings. It adds up fast when you do a lot of shopping.
