Ad Free Yahoo Mail - receipt/bill/invoice information, URL

If you are an Ad Free Yahoo Mail customer and didn’t get a receipt for your bill, and you need to find information about that bill — an invoice, receipt, anything related to the payment — as of mid-2016 you can find your Yahoo payment information by starting at this URL: https://payments.mail.yahoo.com

It took me a long time to find that URL today, so I thought I’d share it here. (I could not find any way to see my Yahoo payments through their web mail interface, or any “settings” or “account” links.)
