    • What are the associated shipping costs if I were to order a machine?
    • Is shipping too expensive or beyond my budget?
  • Service and technical assistance
    • Is there a dedicated service or technical department that I can contact with any machine questions or if I’m having an issue with any of the equipment?
  • Add-on options
    • Does the company you want to buy from offer the add-ons (trailer, decoiler, reel stand, power pack, etc.) that you want to purchase?
