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.
