The internet seems to be the first point for people to refer to when they feel the need to get information on something or even to find solutions to certain problems. More recently however, people have been moving away from looking for discounted items to hunting for freebies and one of the things that you will often find people looking for would be the free xbox live codes which allows them to buy add ons to their games or even to get newer games. They would have otherwise been expected to spend money which is often in the form of charge cards in varying denominations. So, it would be a good idea from your part to look for proper solutions to any of the problems that may face you from time to time.
When looking for free xbox live codes online, you will have to keep one thing in mind. That is, not all codes would be available for free or where they may really be available for free, they may not be for everyone to go there and claim.
It depends upon the website that makes these codes available as they may require that you complete surveys to help them understand consumer demands better before they could share these codes with you.
