Free MS Points
There are many ways to get ms points for the Xbox Live Arcade, but they all require you to pay for them. I have the only method for which you can get free ms points sent to your email in under a days time! These are legit codes that you can enter on Xbox.com or in the Xbox Live Marketplace by yourself. I will never ask you for your email address, gamertag, or password. This is legit. These free ms points codes are available to you. Just follow the simple directions and you'll be on your way to your free ms points.
Step One
Sign up for your free account at the Rewards site. Make sure you enter correct information. they will never mail or call you, and the only emails they will send you are the verification email and the free ms points. Once you have signed up for your account, head on over to your email to verify your account. This is step one of two for you to get your registration bonus. Once you have confirmed your email, head on to step two.
Step Two
Once you have your account ready to go you will be able to proceed. Click on the "earn points" tab at the top of the page and then select an offer to complete. I usually click on "earn points" and then "free offers" because they are both easy and free to complete. Read the information about how to complete the offer if there is any, and then click on the offer. Complete the offers requirements and then mark the offer as completed. It will take you a little bit of time to get used to what you need to do to complete the requirements, but once you get the hang of it you can do them quickly and easily. If you have any questions with the offers or anything at any time, you can usually post in the shoutbox and receive immediate help from those who know what they are doing. Use this to your advantage, they can help you get the hang of it. After you have been credited with your first offer you will receive the registration bonus of 250 points! This is about 1/6 of the way to your first 1,600 free ms points card.
Step Three
It will take you an hour or so to complete the necessary offers required to get the points you need. Once you have completed enough offers you will be able to request your free ms points. It's that simple. Once you have requested your free ms points you can either continue doing surveys in order to get more, or you can save up your points and get other prizes like xbox 360 controllers, xbox 360 headsets, xbox 360 games, or any other amazon product imaginable. Again, if you have any questions, ask them in the shoutbox and they will be answered! Good luck, and enjoy the free ms points.
