I need a purchase invoice for a purchased item

Question

In previous days I bought a new telescope, the seller has not sent me an invoice, I need the invoice to import it to a country outside the United States, the seller tells me that it is a third party (etsy) who should send the invoice, but I do not know who it is (etsy) and also I have not done any business with them. What could I do to obtain said invoice?

You may be able to use the "order details" link from that transaction from your purchase history as a sort of invoice for a transaction. There is a printer-friendly version of the page.
