Early Order Cancellation

All deposits are non refundable. Lots of our products are special orders and in many cases your order has to be built for you at the factory. This is what makes a lot of our products special. Once your order is started, it's being put together just for you. For this reason we ask that you don't cancel your order after you place it with us. If for some reason you absolutely have to cancel your order with us, we will assess you a 25% cancellation charge. This amount is equal to 25% of your total order amount. Ask us before you place your order to see if what you're purchasing is considered a special order.

Do not accept your shipment if the package shows any signs of external damage. After the item is returned to us we will ship you a replacement. If you receive incorrect or defective merchandise, please call 781-335-0700 within 5 days for a return authorization number.
