GCs - How are you using the pricebook?

Most of my projects are all different. Even something like a fence gate is different from one property to the next. One place the gate itself is going on the wall, the other it's going on a post and the current post is wobbling. All bathrooms are roughly the same, but maybe the tile is different, or this customer wants to buy their own supplies. etc. 

So for you businesses that are in this pickle, how are you using your price book?

I basically use mine for line items that don't actually carry a price - policies and warranties for specific things (paint matching, bathroom remodel discoverable, etc) but I'm not using it for what I'd imagined are it's intended purpose. Looking for a little coaching here!
