Good addon for the initial plugin

Really good product that makes it easy to reverse redeem orders. We had some problem with installing, but I wrote to the support that was really fast to answer and help. I also had some other questions according to their other plugin PDF Vouchers that we have been using for 2-3 years now and they were also very helpful and explained, even with skype! So I am very happy and satisfied with booth plugins, they work really good and are so useful in our business. Thank you!
