Automated Craigslist searches

I'd like to thank Lifehacker for the tips on becoming a Craigslist power user. I've purchased a few items from Craigslist and gotten some freebies, but sometimes what you want isn't immediately available. And if you have a little time, that's no problem.

What was news to me is that every Craigslist search has an RSS feed. Every time you search for "weber grills" or "beanie babies," a little orange link at the bottom of the results page says "RSS." Copy that to your favorite RSS reader and - voila - real-time updates on the availability of your item.

Neat!
