do coupons stack with already existing steam sales, like could I use my 33% Valve coupon on Portal 2?
No, since they count from the 2nd of January onwards. (until somewhere in March).
Also, trading using the steam forums is exhausting and takes a lot of time until you actually get a good deal. Unless you have some pretty sweet gifts, I guess.
