Show HN:Giggilyzer, beta version of a book re-selling app

Hi, I'm leading the open beta testing for Giggil's free iPhone app. It's a free, lite version of the heavy-duty scanners book scouts use. It uses the phone's camera instead of a scanner, and doesn't list the listing price, but the profit of sending the book to Giggil to sell/ship. I would very much appreciate you guys' feedback.

The app can be downloaded here: http://bit.ly/iQQ061

Though you can post your opinion in this thread, I would also value your email address so I can send more specific questions. It'd be awesome if you made an account, the easiest route being our website: http://bit.ly/mTWTDP

Thanks
