If you have a coupon code to use with your VSCO Workspace subscription, you can add it while creating your new trial account:
If you have recently signed up for a new trial account but forgot to add your coupon during sign up, reach out to us in Support from inside your Workspace account, and we'll check if that coupon can be manually added. Not all coupon codes will be available to add after sign-up but definitely reach out to ask!
