Shopping on Black Friday is actually OK if you're getting necessity or useful items because there can be good prices or deals on them. And the good thing about hunting for those type of items is that you don't have to camp out or go extra early to get them because they're normally available during that sale period.
It was never worth it to camp out for material goods with a limited quantity per store. Most of those TVs were generic or in-house brands. It's not like they were offering a Sony TV for half price or less. Now if they were offering a Sony for that low price, then it would be worth it if you really needed a TV.
