I just ordered two $10.00 Starbucks GC from Nielsen Mobile Reward program since I had enough points.
I joined this program last October.
If you have iPhone or Android, you can join the program.
It's simple. Once you sign up with the program, you install the apps to your phone. That's it. Every months you can earn points. When you get enough points, you can redeem your points with gift cards, jewelry, or other items on their catalog. You can earn at least 165 points every months. Just keep using your phone over WiFi.
I wanted to introduce this program after I prove their legitimacy.
