This theme is priced much higher than the average theme so it can cover the costs of continuing development. Unfortunately Envato does not offer the ability to charge for updates or for a subscription to the theme, which would be better ways of charging customers for continued development. If you feel this price is too high for you I suggest looking for another theme such as my best seller Aardvark for only $55. Buddy is a lightweight, modern and fully responsive WordPress and BuddyPress theme that can be used for any type of website, whether it be business, corporate, community, magazine, portfolio, etc. If you want to use the theme without BuddyPress or bbPress it works great too.
