Price and Format
- Show buy-now price, current bid, reserve status, offer setting, quantity, and whether a listing is ending soon.
- Unavailable items keep a find-similar action so buyers always have a clear next step.
- Won, lost, sold, and cart-ready states stay visually distinct so reviews and checkout actions appear only when they make sense.
Proof and Condition
- Cards compare slab photos, cert area, surface notes, corners, edges, reserve state, and seller notes.
- Electronics compare serial photos, benchmark notes, included accessories, packing proof, and return setting.
- Sneakers compare size, box photos, outsole condition, pickup timing, seller policy, and issue window.
Seller Confidence
- Seller rating, completed sales, response speed, open issue rate, return setting, and hub history stay beside the item.
- Buyers can open a seller profile, ask an item question, follow the seller, or compare another seller without losing the tray.
- Review links stay limited to completed purchases and won auctions.
Handoff and Protection
- Compare hub pickup, local pickup, packed shipment, insured shipment, pickup window, and support path.
- High-value items can show hub check, chain-of-custody note, packing proof, and report requirements before checkout review.
- Issue-risk cues explain missing proof, distant pickup, expired offer terms, or seller response delays.
Buyer Actions
- Watch and like collapse into one saved action so the buyer does not manage duplicate signals.
- Buy-now items can move to cart review; auctions open bid controls; sold or ended items open similar results.
- Compare choices can be saved as a named set for price alerts and later purchase review.
Checkout Hand-off
- Cart-ready items link to checkout review with seller terms, handoff choice, proof status, and payment boundary copy.
- Auction wins should open order review only after closeout, reserve, and bidder eligibility checks pass.
- No payment credentials, addresses, or private documents are collected on this demo route.
