Why dont you just make them available for free, and request donations?
This way the community benefits way more
(I made all my projects free too since I switched to Unity)
oh yes you're right, but the problem is i haven't a visa or master card. so
40 or 50 euro is not an expensive price
5 days ago i sold the browser (50 euro) with all source code , I hope those who bought it, make them faster and better .
