ADD-ON INSTRUCTIONS: To add an add-on to your pledge, follow these steps:
Press the 'Manage Your Pledge' Button above. If you have not pledged yet, it will say 'Back this Project'.
Increase your pledge in the 'Pledge Amount' box by the total of the add-ons you want to add.
If you want multiples of the add-ons, just pledge the amount for the total number of add-ons.
After the end of the Kickstarter campaign you will receive a survey that will ask you questions so that you can explain how you would like the add-on money assigned.
