If anyone else may be in the market for O9A, and you currently don't have any Ozone products, with this Winter2020 code at AudioDeluxe you  get Ozone 9 Advanced for $132.98 if you happen to own any paid Izotope product. Thanks @locrian for the heads up. If you got one of those "Elements" products as a free promo from a Plugin Boutique purchase some time ago that would work.  https://www.audiodeluxe.com/products/audio-plug-ins/izotope-ozone-9-advanced-crossgrade-any-paid-izotope-product-incl
