I need a receipt that I purchased a song to tunes store can I get a copy email to me?

Stevan,

An email receipt was sent a day or two after the purchase.

If you no longer have it, find the song in your Purchase History and click the "Resend" link (see blue link in photo below). A new email receipt should arrive almost immediately.

Have you check your mail box?
