In an effort to lure people into purchasing the Nexus 7 tablet, Google has been giving customers a $25 credit on the Google Play store. Those still on the fence about purchasing a Nexus 7 are encouraged to act quickly, as Google’s terms stipulate that the promotional credit will no longer be offered after September 30th. Customers who’ve had the $25 credit added to their accounts have until September 30th, 2013 to use their promotional balance, which is good towards apps, books, games, movies, and TV shows.
