I couldn't see anything in the rules against this, so sorry if it's wrong. Delete this if it is.
I bought Darkbasic Pro a while ago for £55, and maybe used it 3 or 4 times. I never really got into it-when I bought it I was big into 2D game development and wanted to try something easy for 3D-but soon afterwards I lost interest and went into application development which DBP isn't really designed for.
So I noticed it today and thought, "hey, I don't need this, may as well sell it".
It's going for 23.99 since amazon wouldn't let me list lower.

I posted it in here since I thought DBC users possibly couldn't afford DBP, it was certainly expensive when I bought it
