How do activate the Battlefield 3 Physical Warfare Pack?

I pre-ordered Battlefield 3 on PS3 and got a code from game stop of the physical warfare pack. I just wanted to know how to activate it. Your help would be highly appreciated. Thank you.|||You just need to go into the redeem code screen and then enter the code. You just need to press triangle on one of the screens to get there. I didn't get the Physical Warfare pack, but the game is still really fun anyway.|||Open up Origin. Towards the top after you've signed in there will be a gear with a drop down arrow. click on the drop down arrow and then scroll down to the redeem product code link. click that and then type in the code for the physical warfare pack.|||It's on your receipt.



Then go to "Store" in BF3, and you should be able to press "triangle" to get to the Redeem Code page.
