This year Steam has granted us with more Christmas discounts but this time they added a little "fetch the achievement" game.
Every day Steam selects six achievement that range from "open your inventory" to doing some in-game achievement. Once completed you are awarded with a gift or a lump of coal. You can trade 7 lumps of coal for a gift which is either full game or a coupon, games and golden coupons can be used immediately while regular coupons like the lumps of coal must wait until the event ends.
Honestly i don't see the purpose of the coupons, so far i have gained 3 of them and the discount they give is smaller than the ones Steam...
