I have one in hand it looks like the same deal on the website. The expiration is 12/31/13, maximum benefit $100 per EpiPen 2-Pak where applicable. Not applicable to any federal or state health plan. Offer may be used up to three EpiPen 2-Paks per prescription. Can be used on multiple prescriptions. It's through Emdeon Therapy First Plus.
Doesn't say a limit on cards per family or household. I'm going to call for another.
