Please note: since the demise of Createspace, things are pretty whacky-busy here. We try to answer every single email the same day that we receive it, and send out quotes within 24 hours, but sometimes, we're just slammed. Please be patient, but if you haven't heard back from us in 24 hours, please DO follow-up, because that may indicate that we did not receive your inquiry. Thanks for understanding and being such GREAT customers.
