Here's your answer from an GA Ninja. Yes I took Avinash's course!
Advanced Segments > Custom Segments > New Custom Segment > Name: # of Orders Completed (or whatever you want) > Include > # of Orders Completed (Goal X Completed) > Greater than Zero. Save the segment.
The bold is going to depend on what you call this. I label mine # of Orders Completed because that's exactly what I want to know. I don't want to know about stupid percentages and I don't want to bust out the calculator every time.
Traffic Sources > Sources > All Traffic. Don't forget to have your advanced segment checked off. All the "visits" are the # of Orders Completed.
Wahla!
Mark this as good answer.
