When you secure your order of CytoShield Pro with your credit card, you'll be billed that selected choice rate. After your term, we will automatically bill your card the lowest renewal rate we offer. With this auto-renewal feature, you'll lock in the lowest available price and guarantee that you'll never miss an issue or a recommendation of CytoShield Pro. This auto-renewal feature does not obligate you in any way; you may opt-out of auto-renewal at any time after this purchase. And you may still cancel within the first 90 days to receive a refund.
