AmazoDeals for Android
AmazoDeals lets you browse through the current and upcoming Lightning Deals on Amazon.com without being tethered to your computer or navigating through with your browser. What's even better is that it also lets you set search terms for the items you're looking for, and when a match comes up, your device will automatically let you know.
And when you get that notification, simply follow the shopping cart button to the Amazon's site to buy your stuff before it disappears! It couldn't be any easier.
