wife and I would sometimes go to a friday night public auction, 1 night they had several 6-packs of new screwdrivers (still sealed) high bid was $4, the auctioneer asked the high bidder how many packs he wanted, then offered them to the next highest bidder at the same price, and then offered them to anyone who wanted some. As there were still several left over, the auctioneer said "lets run them thru again", the 2nd time the same screwdrivers sold for $5. Amazing
