Haltech Nexus S3 ECU (universal)
80% de los productos en nuestra tienda están en stock interno o externo, lo que nos permite procesar tu pedido con prontitud (entre unas pocas horas y varios días laborables).
Evidentemente, es posible que un producto tenga un plazo de entrega (inesperadamente) más largo.
Después de recibir tu pedido, te informaremos al respecto y, si es necesario, te ofreceremos alternativas disponibles. Mantén un buen control sobre tu buzón de correo.
Proporcionamos información de stock deliberadamente después de realizar tu pedido, ya que muchos proveedores no disponen de un sistema que permita sincronizar estos datos. Además, no queremos mostrar “estimaciones” como muchas otras tiendas online, donde finalmente acabas recibiendo un plazo diferente o más largo del que se indicaba inicialmente.
Queremos darte únicamente información real y actualizada en el momento en que procesamos tu pedido, para evitar cualquier forma de confusión o desinformación.
