Similarly, if you want to grab a specific auction item on eBay, you can get an RSS feed for any search that you'd like to make on the site--as well as for specific eBay shops.

These are a few of my favorite creative uses of Google Reader. Once you start looking for RSS feeds, I'm sure that you'll find ways to use them in your daily browsing. For more tips, check out our primer, "Getting Started With RSS." If nothing else, Google Reader is a great, free tool for aggregating everything you want to keep track of online in one place.
