For those that pre-ordered Pets, then you should be able to register your game in order to receive the limited edition Pet Shop.  Our friends over at Sims Planet 2 posted a few pics of what the store looks like.  Those that didn’t pre-order the game and want the shop – it’s already out there.  I’m not going to give you any links on where you can find it, but I’m also not going to stop anyone from posting where it can be found either. 😉
