Categories will help with filtering your Pricebook. They make prices changes much easier if they are setup correctly. Categories can bet set up in Pricebook while you are adding items.
There are 2 types of categories Major and Minor
Major is for large groups of items.
Minor is a sub group of the Major category
An example may be Coca Cola as a Major and 20oz drinks as a minor. In that example (which is on the screen shot below) if you received a price increase on 20oz drinks from Coca Cola, you could filter your Pricebook and change the prices very quickly.
Please click on numbers to get descriptions and instructions for Categories.
