The templates / plugins and Joomla Extensions on this website are distributed as donationware. Donationware is software for which only you set the price. You give what you think his software is worth. Zero if you want. I would welcome whatever donation you feel is appropriate. Please note that a few of the components I use may not be used commercially. This is stated clearly on the related template pages.
