What is a replenishable product?

A product you can restock and resell repeatedly, not a one-off clearance find.

A replenishable (or "replen") is a product you can buy again and again at a workable price - everyday goods a retailer stocks permanently, rather than a one-time clearance lot. One good replen can quietly outearn dozens of one-off flips because the research cost is paid once and the reorder is routine.

Building a replen list is the compounding part of arbitrage: each scan is not just this week's deals but an audition for the permanent roster. Rank history over months, stable supply and a defensible price are what qualify a product for it.
