I am usually an opportunistic commissioner (like if I see a tweet that says, "Hey! I'm doing $5 icons!" or something like that). But on the flip side, I've actually been using the commissions tab and have had good response to it. I just wish it were a little more prominent. But maybe I need to make a price sheet to go along with it.

I think the key is finding a balance between "This sheet answers most of my commissioners' questions" and "This is just a massive info dump." It can be tricky to find a happy middle ground there.

I like price sheets that show the individual levels on the same image. What I like about those is being able to see the differences in appearance with each quality level.

Here's an example of one that I just found randomly: http://www.furaffinity.net/view/7423909/

In addition, I like to see the "specialty" options such as icons listed as smaller thumbnails. I like that those give you an idea of what all is available.
