coupon discount

Hi, I bought Parallels 15 for my old Mac, but I plan to buy the new version, Parallels 18, for my new Mac. However, the price is too expensive. Does anyone have a coupon that they are not using and could share with me? @Bhargava@Parallels can you help me :D. Thank you very much

I am writing from a 3d world country, and I would like to ask whether is it possible to get a discount since i am paying the subscription from my bag and not from a my university. thank you in advance
