WAMP is SellerAmp's sourcing analyser for Walmart Marketplace. A Chrome extension shows profit calculations, historic price and sales charts, Buy Box analysis and restriction badges for Walmart products, so you can check a Walmart flip the way SellerAmp checks an Amazon one.
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 Tactical Arbitrage: automates online arbitrage sourcing; for WAMP: free during beta) weighed against its main drawback (expensive for beginners versus walmart only).
