Ok so here's the story..
I have a friend who in his spare time wanted to learn a new language (F#). So what he did was he grabbed a book and wrote a tool which he then released to his teammates. He got plenty of good feedback and encouragement from it. Eventually he released it as an open source. And it was well received. It is now on its 9th month and it has been downloaded around ~6000 times (at an average of 21 downloads per day!). I know that he's been very happy that a lot people found it useful and that he was able to help many of his fellow devs. I also knew that he wasnt expecting to make money out of it (which is why he released the tool as open source). Later on though, he added a Donate link because he wanted to buy a new laptop. Naively, he thought people would actually donate money just because they found the tool useful. Its been 9 months already and he hasn't received any donation so far. (I wish people he'd helped would donate because there are rumors of job cuts in his workplace due to the economic crisis and they might let go even the good deelopers like him)
Now I'm in the same position as him. I also have a tool that I've created on my spare time which my teammates have found useful. I would like to share this tool with everyone but I also want to make a little money on the side. The extra income will go to my graduate studies fund. But going by my friends experience, I cant release it as open source and expect donations. So what i'd like to do is sell the tool at a very affordable price (I'm thinking $10-$15, or lower)
So my question is, does anyone here know of any reputable sites that can sell the tool on my behalf? I feel that rolling out a new e-commerce site just to sell a single, low-priced tool is overkill.
Thanks for any response. :)
EDIT: Stackoverflow, your response has been awesome! Thank you very much
