OK, so if "the doorbuster specials" is -- apparently, AFAICS -- common-enough terminology for the meeja to use; probably invented by the retailers themselves (where did they get it for this article, if not from the shop?)... If that's the way the shops themselves are hyping it, then WTF are they surprised about?
They -- retailers and shoppers alike -- got exactly what was advertised.
Also, I suppose you were feeling -- and wanted us to feel -- all, "Awwww, poor Granny... She's 73 years old, and all!" -- at least, that is obviously the way one is intended to feel, from the article... But I (in stead of feeling as prescribed) can't help notice that the old biddy apparently felt herself spry enough to join the (well-known lunatic) spree, at frigging 5 AM.
Stop to think about that for a while.
