During the majority of the year, stores typically offer deals, promos and coupon codes that last a full week—or at least a few days. However, when December rolls around, stores begin to aggressively pursue flash deals like 24-hour sales and early-morning doorbusters, which can be easy to miss. To ensure that you don’t end up kicking yourself for missing deals on those must-have items, check out the following apps and sites that will do all of the work while you kick back, relax and wait for the deals to roll in:

1. PriceGrabber

PriceGrabber, which offers an app for both iPhone and Android devices, allows users to search for products by brand, description or barcode to locate the best price. If you’ve got your eye on a specific item, simply set a price alert on that item and you will immediately be notified when the price drops! PriceGrabber also offers other useful features including product reviews from other PriceGrabber users and the ability to find products locally.

2. Dealnews

If you’re always on the hunt for the latest deals, DealNews actually allows you to browse through their latest deals, which update each day. These deals include everything from electronics and toys to shoes and more! If you see a deal that you’re interested in but don’t like purchasing merchandise on your phone, simply save the deal to your Dealnews account and access it once you get to a computer. And of course, you can use Dealnews to set alerts on products and get instant notification when the price changes. Dealnews is free and is available for iPhone and Android devices.

3. Google Alerts

You probably use Google everyday to search for things on the Internet, but you may not be aware that you can actually use Google to save some bucks! Google offers a free service, Google Alerts, which allows users to set alerts for specific products, coupons, topics or anything else that you may be interested in. In the past I’ve used Google to alert me to price changes on televisions, books and toys. In fact, I even managed to score board games for $1 thanks to Google! One of the nice features of Google Alerts is that you can set it to alert you as frequently as you prefer—you can get instant notification or you can choose to get all of your alerts once a day. To find out exactly how to use Google Alerts, check out our step-by-step guide here.

4. Springpad

Springpad is actually a personal organizer app that offers numerous uses, including creating task lists, organizing recipes and, you guessed it—price alerts! Springpad organizes your items onto different "notebooks" that are each customized for specific categories (similar to Pinterest). If you see an item that you like, simply "spring" it to one of your notebooks. From there, Springpad will allow you to check prices elsewhere and set up alerts in case you’re not ready to pull the trigger on purchasing. Springpad is free and is available for iPhone and Android.

5. Hukkster

Hukkster, one of the latest shopping tools to hit the web, was recently created by two former J.Crew employees who wanted to help shoppers score the best deal possible. To use Hukkster you will first need to install the Hukk It Button to your browser, which will display a small icon on your browser’s toolbar. Next, shop online and browse items as you normally would. When you see an item that you like and want to keep track of, push the Hukk It Button and add the item to you Hukks. You can organize your Hukks by category and even send them to friends if they need a few hints for your next birthday gift! Anytime one of your Hukks drops in price you’ll be notified via the method of choice, which includes push notifications, email or text. Get a text but still not ready to buy? No worries—Hukkster will continue to alert you to any future price drops until you’ve removed the item from your Hukks!
