However, since the bid increment amounts are relatively insignificant compared to the bid size, they are not considered from a strategic standpoint.[155] The highest bidder's bid is sealed, as in a Vickrey auction, but the current winning bid (second highest plus one increment) is displayed throughout the auction to allow price discovery.[156] Because eBay's auction-style listings are sealed-bid, it is usually to all bidders' advantage that bids are made only at the very end of the auction (except for an initial minimum bid, that cancels out a "Buy It Now" option, or prevents the seller from ending the listing early). Early bids will usually not increase the bidder's chance of winning the auction, and will often raise the item's final price (winning bid) for the eventual winner. eBay also allows sellers to offer a "Buy it Now" price that will end the auction immediately. The Buy It Now price is available until someone bids on the item, or until the reserve price is met.
