This “deal” caught my attention during my holiday shopping, but I have to credit TechCrunch for hammering home why I found this promotion odd.

Best Buy offered a free download of TweetDeck, the Twitter app for iPhone, with the purchase of select Interscope albums from artists including Them Crooked Vultures, Hollywood Undead and Flyleaf.

Which would be a great deal, except TweetDeck is already a free app. The version offered is Interscope-branded and pre-loaded with the Twitter feeds of its artists, but still: as TechCrunch agrees, it’s a little insulting to the consumer to make a big deal out of bundling something that was already free.
