3. Click the Back this Project or Manage Your Pledge button.
4. If you’re creating a custom reward, set your pledge total to the calculated pledge amount. If you’re building on an existing reward, just add your extra item total to that pledge amount.
5. Kickstarter will add shipping costs automatically (that section is called Your shipping destination* and is a dropdown). So, for example, if you’re creating a custom pledge with 2x the GIR Ultimate Standard Straws 5-Pack and shipping to the US, Your Pledge Amount would be $38 ($19x2 = $38, entered manually) +$4 shipping (from the automatic KS dropdown), and the total charge will be $42.
