Presumably you’re talking about the 500px+Adobe-Photographer’s bundle:
I think that would be something to ask the “Awesome” people to see how their bundle works if you already have a subscription.
Hey! I work at 500px. You'll need to contact Adobe to make sure your subscription with them doesn't automatically renew. Then purchase the Awesome + Adobe bundle from us, and redeem the code we send you on your Adobe account once your current Adobe subscription has expired. Hope that helps! Contact firstname.lastname@example.org if you have any questions or troubles. Cheers!
