Can I link to my website/blog/facebook etc.?

Yes, absolutely! In your Admin Panel go to "Settings" --> "Business Info" and right at the bottom you will find a section called "Links".

Here you can link to any site you want (please remember that it is against our terms of service to direct someone to purchase your products outside of Storenvy). Just write the name as you want it to be displayed in the "Name" box and put the full URL in the "URL" box.
