About Bonus content or Pre-Order incentives:
These are sets or items that come in the form of 16 digit codes that come in either pamphlets on the game boxes or in the form of emails from Origin or another retailer.
These codes are made to be consumed in thesims3.com
NOT Origin. This is very important, because if you do consume it in Origin
IT WON'T WORK and you would have lost your code.
Q: I accidentally redeem this 16 digit code in Origin, what do I do?
A: You will have to call Costumer Support to get a new code, they are instructed to help out on these cases, so they should give you a new 16 digit code for your item. Make sure you tell them what game,what edition and what item you were trying to redeem. Also where did you purchase it.
