If you use an Android tablet or phone, hunt down a specially marked Android robot Kit Kat bar
Each package features a code you can redeem for a chance at winning a Nexus 7 tablet.
There are several reports online that people are getting $5 in Google Play store credit on their first redemption. The Kit Kats are reportedly hard to find in stores, so have fun hunting them. The promotion ends January 31st.
This marks the first time Google, which is known for nick-naming its Android mobile operating systems for smartphones and tablets after desserts, has chosen a brand-name candy for an operating system upgrade.
