AAS Multiphonics modular soft-synth on half off at $49. It's been at that price point before, but this time they throw in the new Modular City Soundpack for free ($19 otherwise).

By the way, I logged into my account and notice that they are offering me the free annual holiday sound pack gift. It is super-generous of AAS to continue doing that. I don't think I've bought anything from them in a couple of years, so this is above and beyond good customer service.
