Seen a reward you want more? Or want to combine rewards?
Basically you can only back one reward tier. But you can do the maths manually (add up the 2 reward tiers) and pledge for that amount, and put a note in your pledge for the 2 or 3 or 4 different rewards you'd like to receive.
Officially Kickstarter says: It’s only possible to pledge to a project once. Accordingly, backers can only choose one reward tier per pledge. You can, however, change your pledge amount and reward selection for as long as a project is live.
If you'd like to change a pledge amount or reward selection, just click on the project title next to the corresponding pledge and select edit next to your pledge amount.
Thanks for your support!
