Went to SteamDB and logged in. I checked my Steam wishlist and found three or four games that had hit an all-time low and bought those. In case there's anyone out there that hasn't used it, It's a good tool to use.
I've got a couple of pages of wishilsted games that have matched their all-time low that I will consider. Most of them are that same price each and every time they are discounted, but I might pick up a few of those that I may want to play soon-ish.
I know it's a tired sentiment, but man I miss the days when the first ten minutes of the Winter Sale would mean a dozen pages in this thread. Glitches made it exciting. Frequent price drops made it exciting. What it has turned into is the complete opposite of exciting. Sorry, but new backgrounds and avatar frames just don't get me going.
