To take advantage of the offer, you have to download the free Isis Mobile Wallet and bring your smartphone to any participating Jamba Juice store to pick up your free drink. The app allows Jamba Juice customers to tap and pay at any location but is only available on select smart phones.
The offer is good through April 30, 2014 or until 1 million free drinks are redeemed by Isis users and there is a limit of one drink per day per user.
