It's basically an online version of the sticker book except that it's free -
http://en.stickeralbum.fifa.com/game...art_view=start
You get 3 free packets a day which contains 5 stickers
There are some promo codes you can use to get other free packets
You can trade your swaps (haven't tried that yet so don't know how it works)
Me and Drew are already on there, not sure if anyone else is?
I started yesterday and have completed 10% so far. Have Falcao, Modric, Balotelli, Moses, and Rodriguez as swaps.
The promo codes for free packs are:
FIFA-PANINI-PACK
