Market Size & Growth
Competition Level
Very high and structurally stacked against you. In retail arbitrage you compete with Amazon itself and with sellers running automated repricing, while on eBay, Poshmark, and Mercari you face countless sellers listing the same items. There is no moat in buying low and selling high when everyone has the same price-scanning apps.
What Reddit is Saying (Real Signals)
Reselling communities openly describe it as a job, not passive income, with hours spent sourcing, listing, packing, and handling returns for a modest hourly equivalent. The recurring warning is that platform fee hikes and policy changes can quietly erase a margin that was already slim, and that scaling means more hours of work, not more freedom.
Keyword Demand & Search Intent
Search demand leans toward how to start reselling and what sells, which signals aspiring resellers rather than a customer base you own. The buying demand for the actual goods lives on the marketplaces themselves, where you rent the audience and the platform controls the terms.
