I should mention that almost anything I put up here are deals that my professors at school are finding and sharing with the students in my program. Anyway, here we go:
-- Waves is already beginning their sales, for today and tomorrow only. DAWBuster deals is a pretty dumb name, but the only thing I'm going to complain about is not actually having money to buy anything...
For those who don't know, Waves plug-ins are industry-leading in quality of sound... And with the price to match. If you have the resources to purchase Waves products, I envy you greatly.
-- iZotope sales are beginning. Notably you can get a copy of the DDLY delay for free with a purchase of the Trash 2 distortion effect for $29. I personally find DDLY to be a little wonky (but still usable - I should probably use it more than I do), but free is free.
-- Impact Soundworks is having a discount sale on several of their kontakt libraries, including the Super Audio Cart library (the one developed in conjunction with OCR). All their libraries are a blast to use and they're probably the developer that most of my sample library purchases are made with.
