Want to shop but still want to save a penny? Check this app! The AMZ Radar is an app that compares the prices of each item online and provides you the option of which one is the cheapest. What's good about it is that you can buy the item at the lowest price.

Another option that this app offer is that you can check the online price history, shows if a product is overpriced, and shows you items that are on sale. A preview link is also available but just hover the cursor on the item and no need to open each link when checking on an item.
