Would love to get that script, Apple really needs to improve in this area, although I guess for the big sellers it is not so important.
My site is Drupal 6 based and I wrote a module to do the scrapping and populate a CCK content type that I display with a Drupal view. I configured Triggers and Actions for the notifications.
If there are any other Drupal people out there I'm happy to share the code. Just needs a little polish before I could submit it.
