Search for Coupon Codes, Discounts, and Promotions
Google Alerts is great for information gathering, but it's also a great bargain hunting tool. You can set an alert for coupon codes or discounts to your favorite retailer, and then sit back and let the bargains come to you. Not all of them will be of particularly high quality and you'll still have to sift through the results to find something useful. Even so, you'll hear about new coupon codes as soon as they hit the web, and you'll get first dibs on using them.
This is especially useful if you're trying to grab a discount code that's only valid for a few hundred uses, or if you want a 10% off code for your favorite web hosting company or domain registrar. Just set the search term for the type of discount you want (taking care not to be toospecific), set the result quality as broad as possible, and let Google do the work for you.
