Sony's promotion with Edge Shave Gel has a problem (or, how to get free DLC)

Simply go toEdgeShave.comand enter one of the codesreadily available online, fill out some personal info, and you're good to go. We tested it out ourselves and it does work. You can do this as many times as you want to nab the following content, as described by Sony:

* A Killzone 3 Retro Map Pack featuring two popular maps from Killzone 2
* Three Killzone 3 Unlock Points to use on the weapon or ability of your choice
* A customized Chevy Camaro SS %26ldquo;Edge Special%26rdquo; for Gran Turismo 5
* A special %26ldquo;Sniper Blast%26rdquo; in-game power for inFAMOUS 2. The long-range blast has a narrow area of effect to better equip you to take-on the enemy when inFAMOUS 2 arrives in June.
