Hello Doc000, I have let the Marketplace Manager and Assistant know about your issue with the 50% coupon. In the meantime, you can also email store@renderosity.com for assistance. Thank you for your patience and have a great day!
Edit: that coupon is good only for RPublishing items. The Marketplace Manager is sending out a followup to the newsletter to clarify this.
