If you backed us via crowdfunding on BackerKit, we will charge you closer to when your product is shipping. We will email you before doing so. If you would prefer to be charged immediately after placing your pre-order, you must email firstname.lastname@example.org and request this.
Pledging to support our project on BackerKit is crowdfunding just like on Kickstarter. We recommend everyone read BackerKit's Terms of Service before backing.
