Amazon Mobile for Android has gotten a new update today, and it’s added a very useful feature for holiday shopping. It now has push notifications for shipping, so when your item is shipped and delivered, your phone will tell you immediately. It also offers the option of notifying you about lightning deals, if you’re interested. Both of these features are optional in the Settings page and can be turned on and off. You might not even need shipping notifications, since your Gmail will do the exact same thing. Grab the update from the Play Store or hit the source link.
