Pros: If you're not picky about the finished color & sheen, you can cover a lot
of square footage for cheap, by combining paints. I have some friends who recently painted the entire inside of their garage by throwing together "partials" of about 8 different cans of paint. I have no idea how to describe the color, other than that it was "kinda light."
Cons: Unless you're fastidious in thoroughly mixing it, you've got problems. Also, you'll never be able to perfectly match either the color or the sheen.
