Beta testers for book-reselling app

[mwcarper13]

Hi, I'm leading the open beta testing for Giggil's free iPhone app. It scans book bar codes with the camera, then gives you an estimate of how much money you'd make if you send the book to Giggil. (Which handles the shipping, listing, etc and takes out fees for doing so). 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

So I can send your our survey, I'd appreciate you making an account, the easiest route being our website:

Giggil

Thanks
