Can´t follow instructions to buy Edu edition with coupon

The email with the code referenced an image with further instructions to buy MarginNote, but I cant see the image. It just appears a tag with “image”. See image for reference.

As per instructed in the mail, I can only ask for one code and y must redeem it before 48 hours. I have only 24 left.

Thanks man, problem solved.

Much appreciated.
