I came across your website and decided to purchase one of your stickers. I just received it and wow I love it! I decided to put it on my computer at work and so many of my peers ask me where did I get it from... I decided to purchase some for my peers as we are all true believers in Education. I am also going to purchase one of your T-shirts as well. You just gained a new customer" - Lisa
