For those who live in the USA and may not be aware, Microsoft has a program entitled Microsoft Rewards, formerly Bing Rewards. You earn points for completing searches with Bing, using the Microsoft Edge browser and completing other tasks. These points can be exchanged for rewards, including Windows Store gift cards. If you’re interested, sign up here.

The guy has forgot to mention that if you redeem those points, they do expire after some time. So collect points but don’t redeem until you actually want to make purchase. That’s a tip.
