EarlyMiser.com - Feed Based Price Comparison Service

EarlyMiser is an online shopping comparison site that lets you take advantage of low prices in a different way than you might be used to. Instead of hunting across multiple product vending sites to find you the lowest price on a given day, EarlyMiser lets you set up feeds that will notify you when the price of a selected product has dropped below a certain level (or has been reduced by a certain percentage).

To use Early Miser, start by searching for a product. You can search by keyword, tag cloud, or category. When you find the product you want to buy, click "Add to feed" and select the price at which you wish to purchase it. You can add tags to your feed to organize products around it. For example, if you wanted EarlyMiser to aggregate music-related products for you, you might set up a feed called "My Music", and add tags such as "albums", "Johnny Cash", "entertainment systems" "laptop speakers", etc. The publication date on each provider changes in the feed when the price is updated, so keep track of these changes with your RSS feeder to stay informed about price fluctuations. You're not limited to viewing the content of your own feeds either; you can check out others' feeds and corresponding products as well under the "Recently Updated Product Feeds" tab. You don't have to register to browse around on the site, but you will definitely want to sign up if you want to build your own feeds.
