It is possible, at the seller’s criteria. See how it works: the proposals can only be sent to the lots that had no bids. You should click on the closed auction of your interest available on the home page of Superbid’s website. Access the complete list of the lots and see if the one you are interested in is open for new offers. Click on MAKE A PROPOSAL. IMPORTANT OBSERVATION You can only make a proposal on the auctions you are already suitably authorized. Proposals with a value below the initial one will not be considered.
