4x6 Barbie Murders prints?

I'm considering expanding my Barbie Murders line a bit by adding 4x6 shots. Currently I have a sampler of all ten images in 4x6 size, but I just wanted to put out a post checking the interest in singles. They would be $5 as opposed to the $10 that the single 8.5x11 shots cost. Any thoughts? Suggestions? I'd love to hear them!
