Ask HN: new app idea

Just finished reading techcrunch.com/2010/07/07/buywithme-16-million/ when an idea popped into my head. Not sure how original it is but I figured I would throw it out here on HN and see what kind of discussion it sparked.

Recently, I have been stumbling upon more and more of these Daily Deals type websites. However, there isn't really an easy way for consumers to keep track of these websites and check their daily deals without individually bookmarking and visiting each respective site daily. Imagine an app which consolidated all of the websites and listed each sites daily deal. Discuss!
