Two things - when bidding on the auction click the "all items" button to the left of the main page (I don't know about phones)
Please please read the "about" section. It states that the end of the digital auction IS NOT the end of the actual auction. This is just spicing up the pot and the actual auction will be live at the picnic and end at 7p.
Lastly, I'm not sure why the auction isn't going up in dollars. I looked today and someone bid .11 which is fine but I set it to $1 increments. I have a question in to the developers. No matter what it's valid and I will honor it - until I get a response and find out what's up.
