Every now and then someone complains about being charged for skins. It just bugs me alot, so here's something for you to consider:
You buy a car, do you expect to get a new custom paintjob for that car for free?
You buy a house, do you expect to get free wallpapers, furniture and gardening?
You buy Microsoft Office, do you expect to get all your documents typed up for you for free?
You buy Windows 7, do you expect to get all software for it for free?
You buy a stereo, do you expect to get all the music for free?
No, you don't. You KNOW people like to get paid for the work they do.
Now ask yourself: Why do you expect ALL skins to be free?
