About the Hammerdown

Hammerdown converts any product in your Shopify catalog into a timed auction directly on your product pages. Shoppers place bids in real time and watch the action unfold live. The app includes proxy bidding so buyers can set a private maximum bid and let the system bid automatically on their behalf. Popcorn bidding extends the auction end time when bids come in during closing seconds, ensuring auctions only end when bidding stops. When an auction closes, the winner receives an automatic invoice at their winning price, and checkout enforcement prevents anyone else from purchasing that item at the catalog price. Features include a live auction grid page, reserve pricing, buy it now options, runner-up reassignment for non-paying winners, buyer's premium, invite-only auctions, bulk CSV creation, and a bidding API for advanced integrations.
