Since I’m unable to send a direct message to him due to the system’s limitations, could you please convey a message to him on my behalf? I would be grateful if you could let him know that if he is willing to sell to me, please email me.
For my setting, I cannot send a message to him directly, so would you please tell him about me? If you can sell it to me, I would be pleased if you would contact me using this email address.
