I have:
Shadowgrounds (giftable, not a code)
HL2 (anyone NOT have this yet?)
Bad Rats: the Rat's Revenge (NEW!)
50% Valve
33% Valve
50% Fallout: New Vegas (hey, it's 50% off now and the coupon doesn't kick in 'till the same ends, SHAWHEET! - maybe this would be good for someone who wants the game but would rather spend their available funds on other sale stuff)
Will trade for coal or any other offer.
