My damage this sale has been greater than I expected, although a lot of this is from Nuuvem or other places.
For me I spent about $25.
Racer 8 and Penguin's Arena were free from Indie Gala and Bundle Stars.
SpeedRunners was gift from a friend
Alan Wake Bonus Materials were Free on Steam Store.
Fallout Classic Collection 2014 I bought from GMG and used my 22% discount when it was 75% off already.
Jet Set Radio I got from the Humble Store when it was 75% off.
Everything else I bought when it was 75%-80% off the Steam store.
This makes it the most I've ever spent on a Holiday sale - I mainly go for PC games during the Summer sale and focus on console games during the holidays.
