Planta Greenhouses se dedica a entregar su pedido rápidamente, para que pueda comenzar a utilizar sus productos de invernadero de inmediato.

Debido a que los invernaderos se empaquetan en cajas grandes, tienen requisitos de envío únicos, que incluyen:

  • Nos comunicaremos con usted para confirmar el precio de envío, según su ubicación y el tamaño del pedido.
  • El envío para la mayoría de los pedidos cuesta entre $250 y $450. Las entregas a zonas remotas pueden tener un costo adicional.
  • Al realizar su pedido, asegúrese de introducir el teléfono y la dirección correctos al finalizar la compra. Nos pondremos en contacto con usted por teléfono antes del envío. No nos responsabilizamos de entregas a direcciones incorrectas.

  • Haremos todo lo posible para enviar su pedido lo más rápido posible y mediante el medio de transporte que usted especifique. Sin embargo, si no hay instrucciones específicas, aplicaremos nuestro criterio y realizaremos el envío de la manera más rápida y económica. No nos responsabilizamos por retrasos en la entrega debidos a circunstancias ajenas a nuestra voluntad.
  • No realizamos envíos a apartados postales, ya que en la mayoría de los casos deberá firmar para recibir su artículo.
