Auctions and counteroffers: two ways to negotiate price

Auctions and counteroffers: two ways to negotiate price

How proxy bidding + anti-sniping work and how to send counteroffers.

2026-05-24

Three sale modes

  1. Fixed price — "Buy now" button.
  2. Auction — highest bid at close wins.
  3. Private offer — buyers send offers, seller replies.

Auctions

  • Starting price (min for first bid).
  • Close date (up to 14 days).
  • Minimum increment: €1.
  • Anti-sniping: a bid in the last 5 min extends close by 5 min.

Proxy bid: enter your max. GSG bids on your behalf, raising only as needed up to your max.

If you win

48h reservation to complete payment. If you don't pay, the seller can offer to the runner-up.

Counteroffers

When seller has "accept counteroffers" enabled:

  1. Buyer sends initial offer.
  2. Seller accepts / rejects / counters.
  3. Buyer accepts / rejects / counters again.
  4. Max 2 rounds.
  5. Each offer expires in 24h.

Reservations

Some professional pieces allow reservations: buyer locks the piece for X days against a small deposit. Pay within → deposit applied. Miss the window → lose the deposit.

Etiquette

  • Sent offers commit you. If the seller accepts, you must pay.
  • Repeated unreal offers block future ones.
  • Chat is moderated — no external contact.
