The bottom line with this site is that you have to get lucky. End of story. It's as much a gamble as if you were walking into a casino with $60 bucks and pumping into a slot machine that flashes "$1500" at you. I signed up for this site TODAY and won an Apple Macbook Pro for $12.11. I'm not kidding. And it is total luck. Here's how I did it.
I noticed that there is a feature called "Bid-O-Matic," which enables the user to set an automatic bid whenever the clock gets too low. I was initially frustrated by this, because it made it virtually impossible to ever win. Then I clicked on the Apple MacBook that I eventually won, and noticed that everyone bidding on it was NOT using the Bid-O-Matic feature. See, the thing is you have to hope that everyone loses track of the item you want and forgets to bid, as they only have 10 or 15 seconds to bid on it. With the Bid-O-Matic feature, you can set it and forget it. So I set MY Bid-O-Matic, and, sure enough, about a minute later everyone lost track of it and I scooped it up.
It's still mostly luck, and it is not easy to do. It's a gamble. So know what you're getting into before you buy anything. But with a little guile you CAN win the big prize, and I'm testament to that.
