It's amazing to think that there's an app devoted to a specific shopping day — November 27, the Friday after Thanksgiving. In fact, there are a number of them. TGI Black Friday is a free app that gives you access to over 8,000 Black Friday deals from all the major retailers — before they come out in newspapers. You can browse the deals, search for specific items, create a shopping list within the app of those that you want to focus on, compare prices to confirm you're getting the best deals, and more. You can view deals by store or category, and also view the most popular deals. The app is powered by TGIblackfriday.com and DealCatcher.com.
