Auctions

How bidding works

1. Place a bid at or above the current high — minimum increments apply automatically.
2. Get instant alerts if you are outbid; auctions extend by 2 minutes if bids arrive in the final minute.
3. Winning bidders complete payment within 24 hours via SastaGym secure checkout.
4. Sellers cannot cancel after reserve is met — disputes route through marketplace support.
