I've used this for several months with 3 codes and I'm very happy with my experience. The UI/UX is clean and intuitive, so there was very little learning curve which is helpful. I especially like the multitude of options for delivery of digital goods after purchase. This combined with the gift and pre-auth options made going full stack a no brainer for me, so I got the 2 extra codes.
Thanks Zylvie team! Keep up the great work and support on this awesome software!
