In order to learn a bit more about screen scraping with cURL, I coded up a script to generate an RSS feed of Safeway‘s weekly specials. The number of frames and strange redirects on Safeway.com shows that they probably paid some lifeless company a ton of money to develop it for them (Vertis, in this case). I can only imagine the frustration their engineers must have while trying to debug this stuff.
Try it out, and let me know how it works for you: Safeway Weekly Specials RSS.
Btw the code is on GitHub: http://github.com/powdahound/safewayspecials
