Thanks!

I downloaded a font (good karma demo) to be exact. Now, I have a small online boutique, and want to use that font in my logo. BUT I'm not sure whether or not I need to pay something for using it in my logo.
I read that dontaionware means you can use the font commercially with the option to pay. However, in the fonts comments, the owner says you'd need to pay to use it. I'm willing to pay for this font, no problem, Though, I want to know ahead of time what does dontaionware actually mean legally just in case I want to use other fonts that say this. Thanks!
