If you want to ship more than one package to an address at once, you can find the section on the bottom center of the "SHIP" tab to add more boxes.
1. Click on the green ADD button to add another box/shipment. You'll notice that the box dimensions are copied from the previous box so that you don't have to retype the same information. This is especially helpful if you are shipping several boxes that are exactly the same shape and weight. For example, if you were shipping 5 boxes that are exactly the same size and weight, you can enter the information once then hit the ADD button 4 times to get 5 labels to be printed. The labels will created such that each label will show 1 of 5, 2 of 5, etc.
2. You can scroll through all the labels in your list by clicking on the < or > buttons
3. Go to the first label by clicking the << button. Go to the last label by clicking the >> button.
4. Delete any label by clicking the red "DELETE" button when you scroll to that label that needs to be deleted.
