Next week, users of the Starbucks iPhone app will notice significant improvements to their coffee buying experience. The company has revealed that enhancements to the app are in the pipeline and will be released in a March 19 update.

Customers in the US, UK and Canada will be able to leave their barista tips directly from the iPhone at over 7,000 Starbucks locations. Considering that Starbucks reports over 11 percent of all transactions now occur using a mobile device, baristas must be happy to hear that generous customers can easily deliver a gratuity without cash.

Audio books are are a great way to catch up on all the books you want to enjoy but don't have time to read. You can listen to them while you jog, or on long car rides / flights or while you cook and clean, but the only problem is that they tend to be more expensive than the print editions of the same book. For example, the Divergent unabridged audio edition is $14.95, and a used copy of Divergent in paperback is only $5.95 on Amazon.com. Even with shipping costs the print edition is cheaper, but that's where Audible comes in.

Audible is a subscription-based service from Amazon.com which gives members access to more than 150,000 audio book titles. If you listen to a lot of audio books, an Audible membership may be something you want to consider.

It may seem a bit premature to declare Smash Hit the best game released to the Apple App Store this month, but it is hard to believe that something more addictive and entertaining will take its place on my iPhone before March is over. I have to admit that it was a tweet by The Verge, and free price, that led me to download the game in the first place. I hadn't intended to review Smash Hit but after picking it as our "Game of the Week" in our weekly recap, I decided it needed more attention because it is just too fun to ignore.

Smash Hit is an easy to play but challenging game where you must throw balls at glass obstacles that get in your way while flying through different 3D dimensions. You begin the game with 25 balls and can collect more by smashing blue crystals scattered throughout the various levels. The game is over when you run out of balls.

The motto save money takes on new meaning for Walmart customers looking to purchase a brand new iPhone. The company is now offering the iPhone 5s for $119 and the iPhone 5c for just $29. Both deals require a two-year service agreement with AT&T Mobility or Verizon Wireless.

These new prices on 16GB handsets are highly competitive, slashing $26 off the previous iPhone 5s price, and lowering the iPhone 5c cost by $16. Best Buy will get a run for its money, as Walmart now beats its lowest price on the iPhone 5s and 5c by a total of 31 bucks and $21 respectively.

Reduced pricing is the name of the game as AT&T continues to revamp its mobile offerings to battle the competition. Single-line data plan customers are the latest to benefit, as the company is slashing the price of its 2GB data plan. Subscribers can save $15 over the previous offering, with the new plan going for $65 per month.

In addition to 2GB of data, the single line plan includes unlimited voice calling and text messages, unlimited international texting, and 50GB of cloud storage. Users can even add a second line to share the 2GB data pool for an additional $25. This prices the 2GB data plan with two lines at $90 per month.
