Hi Sadie,
It's a packing slip that you remove the prices from.
I ship every order with this type of packing slip since they already got the invoice emailed to them when they placed their order.
You click on Print Order
You'll see Packing Slip - check it - then across to the right in very small blue print you'll see Customize Options. Just unclick Cost Breakdown.
This is also where you can add a personalized note to all your packing slips. Good luck!
