Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.
