Bad idea. I just spent $70 or so, and all I have to show for it is a couple of small items worth about $8.
Here is the trick - you have to pay for each bid. Once you place a bid, it puts extra time on the clock, giving others a chance to bid again. In effect, the item goes up by $0.01 with each bid - but it could cost you 20 - 60 bids to win an item. And, consider that the most desirable items get the most attention (cameras, TVs, Tablets, etc), they are being bid on by multiple people. So, when you see - I got an iPad for $22.48 - what that really is saying is $22.48 in price out the door - and over $1320 in the cost of bids (again, each bid cost $. 60 to place) since there were over 2200 bids made - 2248 to be exact.
Translation - let's say you are bidding against three others for a Camera. You end up paying $14.50 for it, but in the process you have placed 450 bids - you actually just paid $284.50 for the camera. Not such a great bargain after all...
