What you need to do is just multiply the reward amount plus shipping by the amount of rewards you want.
Example: 8”+7”Kickstarter Special is $179 +$13 shipping =$192
If you want 2 of these rewards it would be
2 x $192 =$384. 3 would be $576 and so on.
At the end of our kickstarter campaign you will receive a survey that will ask you exactly what you want for the pledge you have made. You will have the opportunity then to make any adjustments needed.
