The Kickstarter and Indiegogo terms are clear, there are no refunds even if a product is unable to be delivered. Despite that, we'll do our best to accept cancellation requests on a limited basis.
Shipping invoices that remain unpaid after September 30th will be sent a follow up email asking for how you'd like to proceed. Cancellation options will be provided. As your order was custom ordered at cost, any refund granted may have several weeks to months to process.
