Below a summary of the free items to be found in The Sims 3 Store. It is advised to download free items right away cause some items may be removed at some point.
*No longer available in the Store. Will remove it by EA's request.
**Part of a different free Christmas set.
I'm still looking for the IAMS set and sofa. Also looking for the Ford Fiesta set. If you have this, I would be most grateful if you would send it to me. I will post them on the site so everyone who missed these, can download them (will give credit if you want).
Some people say that if you're registered with EA, you will get an e-mail on your birthday with a link to a free pack. Read all about it here: Sims3Forumpost.
However, many simmers say they didn't recieve anything on their birthday so it is unclear if this pack is still being sent out or if it's only available for certain regions.
