    Thousands of second-hand listings watched around the clock: furniture, clothing, sneakers, watches, cameras, electronics, cars, music gear.

  2. 02
    Price

    Compared against listings for the exact same item. Outliers out; fees, shipping and a safety buffer subtracted.

  3. 03
    Verify

    Checked live at that price before it reaches you.

  4. 04
    Post

    Only deals clearing $20 net and 30% ROI make the cut, with the full math attached.
