For those with valid prescriptions and health insurance, EpiPen offers up to $100 off the co-pay of the EpiPen 2-Pak or EpiPen Jr 2-Pak via this printable coupon. That's tied with our mention from last October and continues to be the best deal we've seen on this life-saving drug. The coupon must be presented at the pharmacy when you drop off your prescription. The coupon can be used multiple times, for up to three cartons at a time, and expires December 31.
