As I was browsing Amazon on Thanksgiving weekend, I couldn't help wondering about the authors running their promotions on a holiday. There seemed to be quite a few. I tend to run all my promotions and ads during the week, the logic being that people spend more time in front of their computers during the week rather than on weekends and holidays, when they leave their virtual lives behind and actually go out there and do something fun. I would love to get some feedback on this. How do the free giveaways fare on weekends and holidays, and is there a surge of sales afterward, or just a trickle? Has anyone done both weekends and holidays and weekdays and have the results been pretty much the same or drastically different?
