I did buy a box of misprints from EggCartons.com. They came out to about 27 cents each. But, most of my co-workers save theirs and bring them to me for refills. This way if I run out I have some, and can use the new ones. I also bought plastic because we don't recycle Styrofoam here in our town anymore. They are also perforated so I can just tear it apart and sell 6 if I need too.
