RockDawg is again featured on PennyAuctionCoupon. This time, you get 25 bid bones for just $5, an incredible $0.20/bid - a huge saving for all bidders. RockDawg runs auctions which are not traditionally penny auctions but really interesting nonetheless. If you hit a 'magic number' chosen at random, you win. This auction model means you can cut your losses while hunting for great deals. You can know more about it by reading my interview with Diane of RockDawg.
