How can I view my account invoices?

I believe I took advantage of the reduced pricing from an email I was sent, but I can't find any kind of receipt or proof. Can you help?

I checked your account and the new subscription is indeed at the discounted rate.  Subscription invoices can be found from you account billing page.  Here is our guide on how to view them:
