On the project page, next to the main video click “Manage Your Pledge” Enter a new amount in the pledge amount box. The amount you enter will be the TOTAL amount collected when the project is funded.
To add one Titanium ring, just add $4 more to your current pledge amount.
If you want one additional Hi-Tec-C refill add $5 to your current pledge amount.
At the end of the campaign, you will receive a questionnaire to make sure you get everything you want.
