Don't forget about Cyber Monday! I'm also wondering the same thing as the OP, particularly for software. I got Studio One Producer for $99 last year on Black Friday.
For the synth folks -
SynthMaster Standard for $64.50 doesn't suck.
The Nori Ubukata Historic Synth Giants Volume 2 & 3 for a total of +$16 also doesn't suck.
