I avoid Wal-Mart like the plague on a regular basis (with the only exception being Halloween)... sometimes, it's worth it to find what you want for a little more dinero.
In spite of the super-long lines at Fry's, people didn't really push all that much. I did have some guy back into me trying to turn his shopping cart around. I yelled, "Whoa, there, tiger!" and made him stop so those of us he was running into could give him some room. Silly India-n Man... other than that, and these biotches at Target, there wasn't really an issue finding what we wanted unscathed.
We actually lucked out 3 times this year... at Fry's they were out of the 8G flash drives, but as we were about to walk away... they pulled down a whole box of them! Then, at Target, the same thing happened with the digital video recorders. And at Michael's, they were out of the $5 paper trimmers, but one seriously awesome employee found one mis-shelved... so we got one! Whee! =D
This was only my second time at the Black Friday am sales. Most of the time, I can get what I want in the afternoon, so I don't bother getting up early. I value my sleep too much.
That really sucks to hear stories about people running each other over... those places sound very disorganized. Eesh.
