I am a student and I was wondering if there was separate pricing like with Adobe CC for students/teachers.
Thanks for your question. This is covered in the FAQ:
Are Adobe Stock education discounts available to students and teachers?
There is no educational discount pricing available for Adobe Stock.
I have an education subscription can I still subscribe to Stock? I've been trying to 'upgrade' the $29US account but I keep getting an error.
Yes, you can add the $29.99 Stock plan to a Student/Teacher CC subscription.
What error are you getting? Let me know if you want me to try to process the plan change for you.
