You can Bid on electronics, gift cards, household items, tools, appliances, fashion items, patio furniture, video games and much much more. All auctions start at $0.00 with no reserve prices. I think it is a really fun and exciting way to find unique products at great prices.
Many people get frustrated with ebay because of the reserve prices, but deal dash does not have reserve prices. So, in theory, you could win items for very cheap prices, if you're the highest bidder.
It is a great concept, and great site.
