There will be a charge for this service in which the purchaser is responsible for all costs associated with this assistance. We recommend you pick up your Spat on Shell order given the weight, however for smaller orders, a few shipping options exist.   Options are; 1. You pay a separate invoice for shipping after FedEx calculates costs billed by HPL monthly or 2. You obtain your own FedEx account number and are billed directly from FedEx.  You will be billed additionally for the shipping costs from HPL.
