After making that post I decided to update my database and get it up to date.
Here is the summary worksheet I usually work with.
This is sorted by sales high to low. I can clearly see when a person signed up, when their first buy was, when their last buy was, how much they spent and how many days from signup to first buy.
This is sorted by the number of days between sign up and first buy. Please note that a couple of then took almost 10 years from sign up to first buy.
Then these are a few of the charts I make up just because I like to look at graphic representations of the data.
