The bid must be equal or higher to the reserve price to be considered legal. If the reserve price is not reached at the end of the auction, the seller has no obligation to sell his item. This is the price at which the bidding will start for an auction. The lesser the minimum price, the more users will be encouraged to bid on an item. This auction format is perfect for sellers with many identical items to sell.
Bidders specify both a bid price and the quantity they want to buy.
If there are more bidders than items at the winning price, the earlier bidders will be reconsidered. As a result the items will go away for RM 20. The winning bidders are the one with the highest bid and the 9 bidders who placed their bids for RM 20 earliest. The bid increment is the amount by which a bid will be raised, based on the current high bid. In addition it can be also a flexible increment with no specified interval over the highest bid.
