Cheap or Free Microsoft Points?

I just got 400 points within 2 weeks on Bing Rewards Preview. They change how many points you can get by doing what frequently so it might take you longer or shorter. The good thing is that I only spent about 5 mins everyday to do that. They ended up sending the code straight to my e-mail within a day. The only thing is that you can't do it if you're not in the U.S.
