One of my items was sold to USA. I tried to print my shipping label on eBay/Shippo. However, it said that "You must include one signed original and two copies of a commercial invoice along with your label." My first question is where I should print the commercial invoice. The "Sold" under my eBay, there is no option for printing an invoice. My second question is how to deal with the three copies of invoices. I know that I need to stick the shipping label to my package. Consequently, should I need to put the invoices in a Ziploc bag and apply it to my package as well? Thank you.
