Question: Why there is a "No" Price Group appearing in Quick Price section?
 
 
Answer: This area is designed to get a "quick price" without having to create an estimate or a job.
 
The default price group when using Quick Price is "No" meaning no price group. If you hit the window you will get a drop down of all price groups to select one.
