I know that I have read about Vistaprint's free products many, many times on other teachers' blogs, but in case you weren't familiar with the website, you should check it out! Right now they have a ton of June deals that will expire on July 4th. Business cards, postcards, magnets, notepads... the list goes on. You do have to pay shipping, but it's really not terrible. I wanted to show you the super cute postcards I ordered today!
I borrowed this idea from What the Teacher Wants. Periodically, I will mail a postcard to a student's home to recognize his or her great behavior, good choices, increased effort... you understand. This postcard was super easy to make with their templates and fonts, and it only cost me $6.46 for 100! That is 6 cents per postcard! Hard to beat that price.
