I have been bidding on deal dash and I love their set up. I have nothing but good reviews of how they run this site, it is legit and they stand behind their policies.
I ordered an item and when it arrived it was not what I had expected and I contact them and they worked with me to be able to return it for a full refund.
Give them a try you will have fun and enjoy bidding and hopefully win the item and if not you have the open to buy it out right and get your bids back so it is a win/win situation
