Futureshop Stock Notification Script?

[anonymous2]

I noticed some people using scripts to email notify them of new stock for the Xbox 360. How is this being done? The apps I tried don't seem to be able to read the dynamic counter used for stock on the futureshop website. I'd like to be able to setup something to check for online stock and the instore stock. I know in another month you'll be able to walk in and grab one no problem, but I got some giftcards to burn :)

Thanks for your help!
