Black Friday deals are popular because it's the busiest shopping day of the year. You don't have to get up at five in the morning to be a shopping beast this year because your smartphone can help you find the best deals even if you boycott the shopping holiday. Besides, the following Monday is a popular day for Web sites to have their last minute sales.

There are plenty of shopping apps in the App Store and Android Market, but the BlackBerry App World and Windows Phone Marketplace are somewhat bare in this department. Of course, some of the apps listed here are available on more than one platform, but even if you see an app you like that's not available for your device, at least you can see what the app does and try to find something like it in your app ecosystem.

Some of these apps are free and others are a dollar or two, but all slides in this show include a screenshot of the app and a brief description. Additionally, these apps will work year round, so don't feel like they are made just for Black Friday. Remember to have fun, and tell us in the comments if they work for you or if you have a favorite not in the list. Start the slideshow for the top 10 best shopping apps.
