Great Scout

Great Scout lets you scan and research products for profitability on Amazon.com

Great Scout helps you research items on Amazon. You can scan an item's barcode or search the Amazon catalog to get easy access to the following information: total number and prices of ALL FBA offers as well as all NEW and USED offers, Sales Rank, Rank and Price history, who has the Buy Box, and whether or not Amazon is selling the item.

In addition, it will also show you the fees you have to pay for FBA and merchant-fulfilled selling. You can also use Great Scout to look at general item information such as weight and size, and in case you find something you want to list you can do it through the app, it will also show you if the item can be listed on Amazon.

The first week of using Great Scout is free. After that you will be charged automatically through Google Wallet. The monthly subscription fee for Great Scout is $10 / month.
