It works like this,

You use this website as your search engine (if you want). It's made up of both ask.com and google so it searches both sites at once when you use is. Sometimes, when you search, you get a "point". You can use them to buy things like shirts, hats, snowpants, jackets, etc. It actually works pretty well depending on how much you use it. I have 140 points after using it for about a month (750 can buy you snowpants) and my friend already has 540 points after using it for about a week less than me.
