I need someone lived in U.S. to send a letter for me.
I will tell you the mailing address and what you need to send.
You must send it with USPS Priority mail (which cost you no more than 7 bucks).
My offer will be no more than 10 bucks, including the shipping cost.
You will spend less than 20 minutes to finish the project.
After you shipped the item, you should give me the tracking number asap.
