I like DealDash partially because it is challenging. I would warn everyone to be cautious of their bids, and consider whether they are truly receiving a deal. There are professional users who know how to play the game, and will outbid you until the cows come home (and then some). Add the cost of bids and consider auctions lost- is it really less than shopping around and being patient for a deal somewhere else? Remember when you lose auctions, your bids pay for the winner's item (which is how the "deal" is possible)..
