I don’t know how long it runs but affinity.serif.com is having a 50% off Spring Sale. Their software: Affinity Photo, Affinity Publisher & Affinity Design for Mac, PC & iPad are currently half price and best of all, these are software prices, not subscription prices. I now have Affinity Photo on my iMac & M1 MacBook Air. Publisher is not available on the iPad but Photo & Design are.
