How do the Ticketmaster auctions work?

I'm not too hopeful about them...seems like it's just a matter of who can afford to pay the most for these tickets. Have any of you had success in the auctions?

I've heard talk of waiting till closer to the show to get seats, and as a person attending alone, I'd love to hear how that works too since tickets are so often sold in 2s or 4s.

They've added a second show at the Prudential Cetner and floor seats are available in the front center section!

Difference between Pop-Tarts presale, internet presale, and general public sale?

So, I was really disappointed with the floor seat availability for Prudential Center. I got rows 24-27 a few times in the front three floor sections (A, B, C) but everything after that is kind of crappy. Floor seats, IMHO, are only satisfactory when you're at least row 15 and up and even then...(this is based on previous concerts I've been to).

I'm attending the concert alone so I'm really keeping my fingers crossed for a better seat at the other sales b/c there's sometimes a spot between, let's say, two groups of 4 and 3.

So, I was wondering if the ticket availability increases with the internet presale and general public sale. And what's the difference between the two? I'm really hoping they offer more options than the Pop-Tarts presale. How does that work?

Thanks for answering this first-time Idol concert attendee's (hopefully) questions.

And congrats to all of you who scored awesome tix!
