Overflowing Points
On my iPhone, there is a particular app that awards “M Points” whenever you do certain things in the app; the first time you open it each day, when you watch one of the news stories, that kind of thing. Well, you could trade in those M points for tons of things, including Amazon gift cards. Five thousand M points was a five-dollar Amazon gift card.
Watching a 10-minute video was worth about 300 M points. The trick was that you could drag the bar to the end of the video, and it would still trigger the M points. Basically, you could make about $5 a minute the first day they opened it. My buddy and I stayed up super late that night and made several hundred dollars in Amazon gift cards that night.
The next morning, they reduced the value from 300 to something like 100 points. Still worth it in that you could make a third of the money which was essentially free. The final blow was when they reduced the amount to something like 10 points, then it became too much. In the end, after about a week, we bought two high end gaming computers from nearly scratch.
We already had a tower and power supply for one, but the other was completely built for free, courtesy of this app. It was incredible.
