For those of you in the US of A without the Limited Edition of Pets, here is some good news! Several major retailers still have many, many, many, copies of Pets LE available to order online and on their store shelves.
I have only seen the “standard” edition in a local retailer chain here in Chicago, but after confirmation with them, they ordered from EA post-release. Below are several retailers who still have the Limited Edition, and to be honest, I don’t think they will be running out of them anytime soon.
