A question, I sometimes get is there any way of getting the current price points that sell in my shop? Most people think they know that implicitly but its nice to see what others in this case the computer thinks.
To do this go to register reports.
In sales, select "Turnover by unit price" (marked in red)
Now click Report Criteria and select the dates and departments you are interested in.
I recommend rather than doing all departments that you restrict it to a selected few so you can examine each department on its own merits. In this case, I picked confectionery.
When the report pops up in this case, you can see a definite bulge about $2.50 and another at $16.
If you want to study it farther, I suggest exporting it to excel for additional study.
