How to identify a fake Apple Email

Today I received an email purporting to be from Apple. It contained a link to a (pdf?) that supposedly detailed my purchase. I did not open the link. I have made no purchase. I am pasting in the email text below. Is this a fake or Phishing email, or what?

From: Apple Purchase Receipt #MNWBH8BBHD
Sent: Friday, January 12, 2018 2:29 PM
To: appleid@id.apple.com
Subject: [ Receipt ] - Thank you For Purchasing in App Store.

Detail of your order:

LINE Manga, 360 Manga Coin

You can check detail of your order by opening PDF file.

Thank you. As I said, I did not click on the link and the email itself did not ask me for any information, so I was not certain whether Phishing was involved. I did log in to iTunes and it said nothing was purchased in the last 6 months. Does that also mean that no iPhone apps were purchased? I know that my wife has "purchased" some free apps and MAY have actually purchased some cheap apps for my grandchild. Do they come from the iTunes store or some other Apple site? If a different Apple site, please reply with whatever url to that web site so that I can login and check app purchases.
