As you have noticed, shipping is included now as part of the pledge. The main reason we decided to go this way is that we are trying our hardest not to have any hidden or surprise costs once the campaign is over. This way you know exactly what the pledge amount is right away! There will be NO additional shipping costs past the ones shown at the time of your pledge!
We have also subsidized some of the shipping costs and have tried to provide some discounts in order to help reduce overall costs. We have worked with our freight/fulfilment team to try and keep shipping costs as low as possible, and as is the case with manufacturing, the more we ship (at once) the cheaper per unit it becomes. We have chosen to pass those savings on to you if you decide to get multiple copies!
Don't hesitate to ask any questions if you'd like :)
(Additional items added to your pledge in the pledge manager may increase your total shipping incrementally due to total weight/size.)
