There'a a thread on fatwallet.com about a Dell deal...
"30% off select refurbished Dimension or Inspiron at Dell Outlet"
In the thread there are several mentions of people running a script to auto select Dell systens based on the price / model / features they pass to their script. Then in some cases the script pushes the item into their shopping cart.
There is an example posted in the thread (search for proxy) that uses Proxomitron to do this. But others say they've written similar scripts to do this using XUL or C++.
Now speed is of the essence here. as items are quickly taken by people as soon as Dell offers them up for sale (which happens hourly). So with that in mind how would you write a fast script (that refreshes frequently) to auto shop at Dell Outlet?
Oh and here's an example of the kind of deal scripters are getting...
