Long package shipping surcharge USPS and UPS charge a higher dimensional shipping rate (an additional $15) for packages that are longer than 36". All our speargun tubes are longer than 36" and incur this additional shipping charge. We keep our product prices as low as possible, while maintaining a viable margin to be able to continue offering our customers high quality products and service. For this reason we must pass this additional shipping cost on to the customer. It's a one time fee, adding more speargun tubes to your cart will not trigger it again. In other words whether you buy one tube or 3 tubes, there will be only one $15 shipping surcharge.
