Amazon's own Seller app lets you scan barcodes to check whether you are allowed to sell an item, estimated fees and current offers. It is the first tool every new Amazon reseller should install.
Tactical Arbitrage (now part of the Threecolts Seller 365 bundle) scans retail websites and matches products to Amazon listings to find profitable price gaps automatically. It also has reverse search and wholesale manifest analysis. It is a heavy-duty tool for sellers committed to online arbitrage.
Retail and online arbitrage on Amazon live and die by data: sales rank, price history, Buy Box competition, fees and ungating restrictions. These tools range from free browser extensions to full research suites. Beginners usually start with one scanner app plus Keepa, and add a sourcing suite once they are consistently profitable. The deciding factors usually come down to each tool's standout strength (for Amazon Seller App: free and official; for Tactical Arbitrage: automates online arbitrage sourcing) weighed against its main drawback (limited historical data versus expensive for beginners).
