The document is a comprehensive guide for Amazon sellers on the myriad ways to discover and evaluate products for resale. It begins by distinguishing product discovery from a viable deal and outlines a core set of research fundamentals—demand, competition, profit margin, ROI, sales rank history, price history, Buy Box stability, Amazon presence, seller count, offer count history, restrictions, IP and hazmat risk, stock levels, variation behavior, product match, and supply‑chain considerations. The guide then details dozens of sourcing methods, ranging from low‑tech manual techniques (manual sourcing, storefront stalking, reverse sourcing, brand, category, and keyword sourcing) to structured online approaches (deal‑site, clearance, cashback, voucher, Google Shopping, Amazon bestseller/movers/new‑releases, seasonal sourcing). It explains how competitor and supplier analysis deepen market insight, and it reviews key software tools (Keepa Product Finder, SellerAmp, BuyBotPro, Tactical Arbitrage, price‑comparison research) that accelerate data gathering. Social channels—newsletter alerts, social‑media, Telegram and Discord deal groups—are presented as lead generators, with cautions about crowding and quality. Throughout, the author stresses a layered workflow: use multiple methods to generate leads, then rigorously apply the research fundamentals before committing to a purchase. The “Warren Reality Check” reinforces that data, not the source, decides a deal’s safety, urging sellers to maintain disciplined decision‑making and avoid over‑reliance on any single method or tool.
