How can I renew support w/o purchasing the theme again?
Thanks for the question. If you would like to renew support, you should be able to do so on the theme's product page when signed into an account that has already purchased the theme.
Here is the official documentation from Themeforest on Extending and Renewing Item Support
I've done that, but the only option is to purchase the theme ( or at least it's the same price as the theme??) I just went back to that page and the new link is there now
