Please keep in mind: We have VERY limited donatable buttons. The buttons we supply to orgs and events free of charge are donated by others who purchase buttons. If your org or event can afford to buy buttons (we strive to keep our pricing super reasonable), PLEASE do so, as it allows us to distribute buttons as widely as possible to those who are not able to afford them.
