Black Friday 2009 Deals: Twitter, iPhone Apps, and more

As you can probably already tell Black Friday is a huge time for websites, so much so that there are now dedicated websites and handset applications which keep us up-to-date with the latest deals.

Not only are websites and applications used to promote the deals but social networking sites such as Twitter are a huge way of promoting deals too.

Two of the biggest websites which keep us up-to-date of the latest and greatest deals are DealNews and BlackFriday, BlackFriday’s site quite often posts about deals way before they are announced by retail outlets.

DealNews have recently tweaked their iPhone application, now the application includes more features, one of which allows users to save items of interest to a shopping list, find out more on MarketingVox.
