What Does "Special Order" Mean?

A special-order product is one that we don't normally keep in stock. We order it from the manufacturer as soon as you order from us. We have great relationships with all the manufacturers we carry, so we can get your special order to you as fast as or faster than anyone else. Remember that special orders are non-returnable and non-cancelable, so make sure the item is right for you. A Sweetwater Sales Engineer can help you decide — call (800) 222-4700 for assistance!
