Amazon has released it app Price Check by Amazon to both the Android Market and its own Appstore. Price Check by Amazon is an app that allows you to compare prices for products across a variety of retailers.
When searching for the product you want, you have the option of scanning a barcode, speaking the name of the product, taking a picture or simply typing the name. Once the search engine finds what you're looking for, you'll see the product page with three tabs. The first and most important is the Prices tab, which aggregates prices from numerous sources. Description brings up details about the item you're viewing in case you want to know more information and finally Reviews, which displays Amazon Customer Reviews so you can see what others think before you make a purchase.
The app is very handy and will prove useful this holiday season when you're trying to buy presents at the lowest possible prices. As mentioned above, this free app can be found in both the Amazon Appstore and Android Market. We've got links to the Market version after the break.
