It could be that adwords advertisers ran out of credit for a space of time, and my site appeared at the number one spot getting the good traffic... ...but I cannot see anything different during these clustered sales times.
These statements seem to contradict each other.
I agree with Receptional- looking at the data related to the specific sales will probably tell you a lot more than overall analytics.
Do you have Goals setup in Analytics? Look in the Conversions section of Analytics.
