Nextag Shopping: Nextag is a deal comparison-shopping site that does a lot of the legwork for shoppers doing research or buying online. Users can just scan barcodes, take a picture or type in a product name to find its price on other places on the Web. For those thinking ahead, the app also allows users to put things on their "radar" for alerts on price drops.
TGI Black Friday: Powered by TGIblackfriday and DealCatcher, this app lets users search for products, notifies shoppers when new ads are posted and lets users save their favorite deals for later. It also gives users a breakdown of how many deals are at a particular store, so you can better plan your shopping trips.
Black Friday App: This aptly named program from DealNews has catalogued the Black Friday ads from just about every major retailer from Ace Hardware to Wal-Mart. Users can search and save ads, see deals by category and even look at a feed of recently posted deals to get a good feel for what's out there on Black Friday.
Black Friday by BradsDeals: Another popular shopping site, Bradsdeals.com, also has a Black Friday app that lets users compare prices and look at copies of the flyers retailers have sent out to show off Black Friday deals. Shoppers can also use this app to plan out their shopping trips and set the date, time and location of any planned excursions.
SnapTell: For dedicated showroomers, SnapTell is one of the fastest ways to see if a product in stores can be found at a lower price online. Run by Amazon, SnapTell has users take a quick photo of the item of their choice and then runs it through an image recognition database to see where its advertised online. The photos work best with books, DVDs, CDs and video games. Users can also scan barcodes for information.
