If it's crap ... We'll tell you
I have a 25%, 33%, and 50% off any valve game, a 50% off Civilization V, a 50% off steel storm retribution, a 50% off farming simulator(lol), a 50% off puzzle world, a 33% off RAGE, and 13 Coal. I would rather keep the coal but might trade.
The coupons aren't good until next month and each coal is an entry into the drawing on jan 2nd for every steam game.
EDIT: For those that don't know what i'm talking about the steam sales are going on right now and they have a giveaway on Jan 2nd for the grand prize of every steam game your top 10 or 5 games on your wishlist or a valve complete pack.
By completing objectives each day you unlock new randomly generated gifts some of them being coupon codes, some coal(extra entries into the drawing), or complete games.
So far besides actually needing to complete a game objective there is a free gift for agreeing to the contest and looking at your steam inventory, one for joining the steam holiday group, and one for trading an item through steam.
Unfortunately, I'm broke as shit right now and have nothing to trade.
If you'd like I can tell you how to earn some gifts for free.
Edit: Added in OP.
