INTERNATIONAL SHIPMENTS
We have a number of shipping options available to us for international shipments; however, no single carrier services all destinations. Cost of shipping is always a factor including reliability of service to your specific area of the world. Accordingly, shipping costs will be quoted after receipt of your order and confirmation by either e-mail or fax. Customs fees and/or taxes may apply. These costs will be at your expense. UPS and Fed-Ex air shipment charges include customs clearance fees and in most cases it is the best shipping option for international shipments.
THhs would similarly apply to other vendors (Triode Electronics, etc).
