Here's a referral link, so in case you decide to do it we both can get some extra points lol. Basically you just register and make an account. If you have an Xbox account just sign in and you're done. After that just use Bing instead of Google when you do your searches and boom, you start earning points towards a bunch of rewards like gift cards from amazon, gamestop, etc. I just use it to get the $3 Xbox digital credit. You can earn up to 15 credits a day if you use a computer, 10 if you use bing on mobile so 25 a day if you use both. Using my example again, the $3 credit is 310 points, so it doesn't take too long to get.
Edit: Forgot to mention, it takes 2 searches to get 1 point, but what I do to make it quicker is put in a long sentence in the searchbox, then press enter. Click on the box again, delete one letter and search again, just keep clicking and backspacing the sentence you put in the searchbox and you'll get your daily credits in like, a minute.
