Google has added a rewards program
called Google Play Points
to the Android app store. The program is free to join and members earn points for everything they buy through Google Play, and even for downloading "featured" free apps and games. Points can be redeemed for Google Play purchases, in-app purchases and discounts, as well as donations to charity. The program has four tiers, with higher levels offering weekly prizes. The program is launching this week in the US, but has been available in Korea and Japan for a year.
