I posted this elsewhere but I think this would be the proper place to post it. I'm going to be buying from the Education store although I am not a teacher or a student. I fall under the following condition: How do I provide proof of this? I realize that buying online, I may not even need to show proof but i would like to be prepared. I am the Treasurer of a private school's parent organization (kindergarten). If I were to buy in the store, what could I show as proof? Thanks in advance!
