I'll admit that I went with my wife to Walmart at 10:00 on Thursday to get $4 blu-rays and some portable dvd players and action figures (ironman and starwars) for the kids. Mostly, I was curious because I had never been to one of these "black friday" deals. There weren't huge lines or craziness but I'm guessing that's because the store was open all day. It seemed really well organized and there were lines for each special item.
IMO.. I don't see a problem with people doing the black friday deal as long as they aren't making purchases they wouldn't normally buy. IE. $25 for 8 star wars action figures.. Normally those things run $10 each so if you've got 2 sub 5 year old boys like I do, it ends up saving you a little on your Christmas shopping. Maybe my experience was a bit different than everyone else's, but I really do think that my 1st black friday experience failed to live up to the hype.
