Track price drops with ShoppingNotes.com
This free service sends you e-mail alerts when there's a price reduction on a product you're tracking.
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?
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.
You can also sign up for a free ShoppingNotes account, which lets you view and organize your alerts, get up-to-date prices, and so on. Definitely a handy little service for anyone waiting for a bargain to come along. Of course, there are loads of other price-watch services--this one just happened to cross my radar. If you've had good luck with another service, tell me about it in comments!
