When the pharmacist brought our the orders out, she had the guy pull each out. On all six pens, the expiration date was in one month. She said I'm NOT paying for these. You go back there and find ones that don't expire into at LEAST July. I was glad she checked. That would have sucked to get to the school only to have the nurse tell us they wouldn't take them because they'd be expired for most of the school year.
