Orders are normally shipped from our facility in North Carolina within 1-2 business days after the payment is made. It is very important that the correct shipping address is entered at checkout. We are not responsible for incorrect or undeliverable addresses. Shipping is automatically calculated using current published rates. Buyer pays all shipping charges. Most orders will ship via USPS, UPS, or Fedex depending on size and weight. We reserve the right to choose which carrier we ship through to offer you the lowest available rate. Due to the size and weight of certain item(s) sometimes we cannot ship using our usual methods (UPS , USPS etc.) We are very experienced with shipments of various sizes and weights, and have longstanding relationships with motor freight carriers, so generally get a very good rate. We will be happy to get a freight shipping quote for oversized/overweight items before the purchase is completed.
