Orders that ship directly from a manufacturer normally have a firm shipping estimate but those dates are subject to change due to manufacturer production, inventory or shipping. We do our best to estimate ship dates but orders shipping directly from the manufacturer can have unexpected delays. We will confirm tracking information when orders ship directly from a manufacturer but may not have updates or estimates beyond the original estimate. Once your order is placed with the manufacturer, it may not be able to be cancelled even if it hasn't shipped yet.

Special Case Shipping Rates

 

Please note that shipping rates are subject to change at any time.  We reserve the right to charge an additional fee in addition to the regularly advertised shipping fee for shipping to remote areas not easily accessible by typical freight carrier means (i.e. islands only accessible by ferry). If your order falls into this category, you will be notified upon receipt of your order, and have the option to complete the purchase with additional fee or to cancel the order.  Please note, these instances are very rare, as most locations are reachable by regular freight. If you have any questions, please contact us!
