Looking for beta testers for book-reselling app

[mwcarper13]

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

The app can be downloaded here:
Giggilyzer for iPhone, iPod touch, and iPad on the iTunes App Store

To sign up, I need you to make a Giggil account, the easiest route being our website:
Giggil

We're looking for 100 testers, and just started collecting testers. The app is not very large and I'll likely send feedback forms several times.
