I choose to not participate in the Black Friday feeding frenzy. Several people that I know love getting up at 3:oo in the morning to wait in line for their favorite big box store to open. Every year they tell their tale of woe about missing out on the "big" sales items.
Most stores list some big ticket items at half price, but they have a very limited number of them. Unless you are willing to camp out in front of the store all night, then race to the electronics department and physically grapple with other shoppers you aren't going to get in on the big deal.
I would rather research item ratings and compare prices on line, check the web site to see if it is available at my local store and print out coupons before I start shopping. Better yet, because so many merchants are offering free shipping and coupon code discounts most of my shopping is done sitting in front of my computer.
If you enjoy the Black Friday camaraderie of shopping with friends and it has become a fun tradition for you, then have at it. But excuse me while I spend my day with a good book and a cup of tea.
