Honestly, that seems to be reserved for the flash sales. Ever since they switched to this unappealing format, the dailies have just been rewarmed leftovers for newbies without a library.
The flash sales are pretty dumb, most of them (if not all and especially the popular ones), will most likely be on the daily deals, only for much cheaper. I remember the last time, The Witcher 2 was a flash sale going for 12.50, a day or two later it was a daily deal for 7.50.
