New releases are being added in larger groups, with the addition and consolidation of the various collections.  The discount for the new releases will remain 15% at the time of their release for at least 2 weeks, allowing for new images to be prepped for release.  I am working on a way to identify the most recent that are discounted, for now, they are listed with the newest images first, you can probably see a visual change in the group that is current and the previous group.
