Eh, I do remember them being very worthwhile back in ye olden days. I remember my parents getting an amazing looking plasma TV back in maybe 2009-2010 era for south of $150 on a black friday deal, back when flat screens were still exorbitantly expensive in most cases. Same for computers and a lot of toys too.

Now it's all like "we just raised our prices last week, now there's 5% off WOWWEEE!
