Avoid buying anything for music production from Nov. thru Dec.
That usually fails when it comes to stuff under $20. I always fall for the loop libraries where you get 10 for $15. It may be another pad or string type Kontakt instrument. Truefire usually has guitar videos for $5. Who knows what Waves will do. Buying up all of the cheap items cost as much as buying something big. I only have 3 CC debts and want to keep it that way.
It's probably not a goal I'll meet. I think I've met only two people that accomplished this out of five forums.
This goal I would also consider it a failure if that money went to buying games. Developers are making that easier since they have become worse making games that can run on average hardware by a gamer's standard.
