Resubscription comment

I like to keep all my plugins, themes etc updated. I note that I purchased adventurous Pro on April 20,2015 so the 12 months has now expired. I have found the 'resubscribe' button (and done so), however this appears to be the same annual cost as buying the theme in the first place! As a single user 'not for profit' educational website that I have to pay for myself, I wish that it were cheaper for me - given that I did purchase the Pro theme in the first place, rather than try to manage with the free version. Anyway, just letting you know and hopefully you might be able to come up with a better deal for users in my situation. Thanks Michael.
