Do any of you shop penny auction sites? If so, do you have any suggestions or a favorite? Comments in general?

For those of you that don't know about them here is an example. I am trying and they recently sold an Apple Ipad, valued at 899.00 for 127.55. Each bid costs 60 cents and it the bid goes up 1 penny at a time. Each bid also resets the countdown clock to 10 seconds. In this auction the bids cost the bidders 7653 dollars.

It looks like you can get some amazing deals if you have timing,patience, and lots of luck. A couple of days ago a 200 Walmart gift card sold for less than 3 dollars.
