Absolutely no! I think the whole idea is simply ridiculous! And as Mark said, just to save a few bucks? I don't think so! On the news the had someone talking about it and said the stores only carry like two items of the said sale... eg. the very inexpensive laptops/pc's, tv's, etc. the first people to come in will rush to grab them (trampling anyone who gets in their way!!) then you are left with the more pricey choices!
I suffer from insomnia, I'd rather stay in bed, nice and warm...
