I inquired about purchasing a single stamp from the Unity Stamp company for use with my students. It was part of a set but I was hoping against hope that they might be willing to sell me a single irregular or something since I just needed the one.
I just got the most delightful email saying they would just send me one as their good deed for the day!!
Check them out by clicking the title of this post and it will take you right to their site.
Thank you, Unity Stamps!
