So the shopping and price matching sites you use don't always note the lowest price on that new thingamajig you're trying to track down for the kids for the holidays, or that new electronic office whatchamacallit. Technology writer Rick Broida (a CNET contributor and author of How to Do Everything with Your Palm Powered Handheld) writes about how to track price drops with ShoppingNotes.com (Dec 5, 2008)
"Want to know when there's a price reduction on that PS3 you've been eyeballing? Or the Amazon Kindle? Or just about anything else sold online? ShoppingNotes.com tracks individual products and sends you an e-mail alert whenever there's a price drop.
"There are two ways to use ShoppingNotes. First, you can copy and paste a product-page URL into the site's Web form, then enter your e-mail address for receiving alerts. Alternately, you can install the ShoppingNotes bookmarklet, which greatly simplifies the price-watch process: when viewing a product page, just click the bookmark."
As I posted previously, I enable tracking for specific pages on the web (such as the the DST and time zone web pages) via RSS feed using free, third party services like page2rss, feedity, feedyes and other services.
