Our Responsive and Tracking add-ons received many new features since their release and I feel comfortable increasing their prices from $19 to $29 each starting on January 1st 2017.
If you purchase a new license until December 31st you will pay the lower price now and half of it for every automatic renewal. Hence, you save more than just $10.
If you made a purchase of the individual add-ons before July 1st 2016, a renewal now will guarantee that you keep the lower price in the future. A renewal adds another year to your current expiry date.
If you purchased your licenses with a bundle, nothing changes for you at all.
