The Eridan Duplicator Extension is a free add-on for the Chrome browser. It is developed by Eridan Company LLP and falls under the category of Browsers, specifically Add-ons & Tools.

This extension provides various features to both authorized and unauthorized users. For unauthorized users, the extension allows access to features such as viewing open VIN codes, determining the type of seller (insurance or dealer), and checking the seller's reserve price. These features are available in the lot catalog and on individual lot pages, alongside bid information.

Authorized users have additional benefits, including access to extended sales statistics, the ability to place pre-bids and live bids, buy lots before live auctions, make offers to sellers, and engage in counter-bidding if the seller's reserve price exceeds their winning bid. They can also add lots to their watchlist and view their bidding history, watchlist, and payments due.

Please note that the "average price" feature takes into account various parameters of the lot, such as make, model, year, equipment, drive type, transmission type, fuel type, engine size, mileage, damages, documents, key availability, vehicle status, auction location, seasonality, demand, and seller type.

The Eridan Duplicator Extension also offers the convenience of HD photos for a comfortable visual inspection of lots.
