just saw an episode where they didnt open the bid and jesse won blind bid for 2100 dollars--but when they open it for the first time the camera was already inside the bin filming out the reaction.WTF
shareThey film from different angles so they could ask em to do it again. Or they could put the camera in their first
shareIt's likely all the bins are checked before being put up for auction, to make sure there is nothing unsafe/illegal etc. They will then re-seal the bin with their own padlocks, so it would be easy to seal one of the bins shortly before the auction and stick a camera man in there to wait.
shareIt's all fake..
shareall the bins are emptied and then stocked with interesting stuff for the bidders to find before being put up for auction
FTFY
