First all Limited Editions get the Pet Shop, next they gave an extra incintive for Origin pre-orders, animal costumes. Now EA is adding a third incintive for pre-ordering Pets from Origin… A FREE STUFF PACK!!! You can choose from High-End Loft, Fast Lane or Outdoor Living. Now I really wish I would have pre-ordered from Origin instead of GameStop.
