FREE SHIPPING LIMITED TIME OFFER: Normally we ship most website merchandise orders the same day as the order comes in. But our backlog of custom work has increased quite a bit over the last few months, and we need to catch up. So we are running a few days behind on shipping some website orders. To offset the inconvenience, we are offering free shipping on all orders site-wide right now. Thanks for your business and your patience!
