Hi there, Stephane! So sorry for the late follow-up on your last reply. Our system was recently updated and this fell through the cracks. My apologies!
To answer your question, we unfortunately do not have a discount rate for renewals. However, we sometimes send discounts through Twitter and in our email newsletter, so it might be worth following and signing up to get alerted when a deal is out there. 🙂
Does this help answer your question? Please let me know and sorry again for the late reply.
Cheers!
Geoff
