Several people have written to us looking for information on how one can purchase multiple rewards at the same time. I myself have had this issue with other projects that I have supported. Unfortunately at this time Kickstarter does not support the simultaneous purchase of multiple rewards. However, the way around this is to simply select a reward and then pledge the additional value of whatever additional rewards that you want. At the end of the Kickstarter period we will be sending around a survey that will allow you to remind us of your multiple purchases.
From a shipping perspective, if you are an international purchaser you can include shipping for one order. (The one with highest cost.) If the cost of your shipping ultimately exceeds that of one order we will settle up prior to shipment. We are not looking to make money on shipping so we will only charge what is necessary to get your products to you in proper working condition. Thank you for your continued support and remember to tell your friends, post about our campaign on Facebook, Twitter, Instagram, Tumblr, Instagram, Pinterest, etc...
