David: Steam Summer Sale
So far I've picked up the Borderlands 2 DLC and Fallout:New Vegas. I'm patiently awaiting the new Civ V DLC to hit half off. Patiently.
In the meantime, I got swept up in to Steam trading cards. People are spending real world money on these things (pennies, but still). I'm not profiting, however. I've been selling off my non-Half-Life 2 cards and picking up HL2 cards on the market with the proceeds. In the end I've got a fully leveled up HL2 badge (granddad fought the war for this) and $0.17 jingling in my Steam wallet.
Until I go to craft the "Summer Getaway Badge". 3 cards left to go...
