I am not so sure prices would be lower. From Atomic Mall...
•Reserve Price: If you want to prevent your item from selling below a certain threshold price, set the Reserve price to the minimum amount you are willing to accept for it. Leave this field blank, or enter "0" to make a No-Reserve auction, in which you are obligated to sell the item, regardless of high bid price.
•Max Bids: The number of bids from unique bidders required to end your auction. Set this to 2 for a quick auction, 5 for a standard length auction, or 10 for an extended length auction. Bidding for a "Max2" auction can produce volatile and unpredictable results! The 5 and 10-bid auctions will tend to generate gavel prices which more closely reflect an item's true market value, as bidder competition plays a bigger role.
•Listing Type: Select "Auction" to create a listing which can only be purchased by bidding on your item and waiting for the auction to end. Select "Hybrid" to simultaneously offer the item in both Auction and Fixed Price formats. A dollar value in the Selling Price field is required for a Hybrid listing, but not required for an Auction listing.
There appears to be an actual "No Reserve" auction format provided.
