The ebay auctions are not sealed, which results in higher
bids, and people placing multiple bids. With a sealed bid
auction no one knows the outcome until the envelopes are
opened and the winning amount read. With the Vickery
auction the high bidder doesn't know the price until all the
bids have been read.
