The price is reasonable, the results are beyond terrific. I actually have 3 types of business cards, and each is unique, all three have photos as the background. Two of my cards are self portraits, one with a puppet, and one of me in the teachers' bathroom that cracks people up. One is just a picture of one of the puppets I made. Believe me your business card speaks volumes about who you are beyond your name, email address and school.
I give them out like candy when I attend workshops/conferences. Having a conversation about a lesson you did, hand out a business card, talking about a cool place to vacation, give out a business card, found supplies that work, another business card.
