There is an official MetaZoo Store Locator that you can take a look at right here.
However, I want to make note that there are some store locations that either do not know about the Store Locator’s existence, or, would rather not be listed on the public Store Locator as it can become too cumbersome.
With that being said, I highly suggest giving your local game stores a call to see if they have any MetaZoo in stock.
