backdraft: I get these "windows" of sales only minutes apart, then hours of nothing. It's as if Google can turn us on and off while still showing our site in the SERPS. That is very strange and an experience shared by other sites over in the UK. I am in the US.
Have you checked times?
Most sites I watch receive increased orders during lunch hours etc, when people have some free time to surf for personal use.
