online would be much more convenient and probably cheaper for you I would imagine.. but I dislike reading any kind of graphic novel of sorts online, it just doesn't quite feel the same as being able to feel the page of art under your fingers.
It may not be cheaper, because of me losing some profits to putting it through a book site. So that would raise the price. If you were to pay me directly, yeah, it'd be cheaper, but ti wouldn't eb the same as being able to read it on something like a nook or kindle from teh book store. An online bookstore would get me more publicity too, but there is just nothing better than a real book in your hand.
