Python for Finance how can I proceed?

Good afternoon,
I bought the course Python for Finance from reed.co.uk
Than, I received this e-mail:

"This is Ned from 365 Data Science. Thanks for enrolling in our Python for Finance course on Reed.co.uk.

I’m very happy you did. You’re our first client there. So as a gesture,  I took the liberty of providing a lifetime coupon for our entire program.

Hope you’ll enjoy.

Your coupon code is:

So, how can I proceed to insert the coupon code?
Could you hel me?
Many thanks.
