How it works

Three steps. Then you buy or you walk.

  1. Write it downCost and what you think it sells for. Photo optional. Takes seconds on the floor.
  2. Get a stampBuy, Hold, or Pass — after Whatnot fees, against the margin you set.
  3. Keep goingSave deals you care about. Ask AI Advisor when you want a second opinion — never required for the stamp.

Straight talk

No fake “it’ll sell” %.
