Have you supported a book already but now want to increase your level of support? No problem.
Before you do upgrade, it's worth bearing in mind that by upgrading you move from one pledge reward level to another. Upgrading does not mean that you get the reward items in the new level in addition to the rewards from your previous level. So please do make sure you choose carefully when pledging or upgrading or you might lose out on the reward that you really wanted.
Follow the steps below to upgrade your reward level.
1.Log in to your Unbound account
2. Go to your supported projects page
3. Find the book that you want to upgrade and click manage project
Scroll down to the upgrade and donate box.
4. You'll be taken to a new page listing the available levels to upgrade to. Just click 'upgrade' on the level of your choice and then proceed with checkout.
