I took a look at Dealdash.com this evening. It's another auction site. I figured it might be like Tophatter.com but the similarity is minimal.
I would *never* try buying on Dealdash. The auctions start at a penny and take about ten seconds to climb another penny. Right there you've lost me. Each auction would take a LONG time to complete!
You have to buy bids from Dealdash before you start bidding. They cost 15¢ apiece. So if you see an item selling for one dollar, it means that the prospective buyers have already spent 15 dollars just bidding it up to that price.
They have items actively selling at prices above $200! That means, collectively, people have spent $3,000 bidding and haven't even won yet! At ten seconds spent on every penny increase in the bid, a $200 item has been auctioning for about 55 hours.
It's hard to believe anyone would be stupid enough to get involved in this thing. But people have.
