Some of my studies still need to be published with a proper blogpost on the SST website, this is work in progress. If you are interested in ALL my available studies, you can have a look on my gumroad page.
Gumroad is great as it allows me to quickly make a new study available and they take care of the secure payment gateway and issue a license key. Making it secure and convenient for all my customers.
