While the campaign is live, go to our campaign page, click "Manage your pledge," then "Change your pledge." From there you can adjust your total pledge amount, switch to a different reward tier (this updates your pledge amount automatically), add any available add-ons, or add bonus support. You can also switch to "Pledge without a reward" if you'd rather support without receiving anything.
Keep in mind: entering a new amount replaces your total pledge — it doesn't add to what you already pledged. You can make these same changes from the Kickstarter app.
Once the campaign ends, changes are no longer possible through Kickstarter. If you need to sort something out after that point, email us at contact@tortugabackpacks.com.
