Bad news if you were looking to purchase the Dark Pit amiibo as Best Buy has confirmed in a blog post that the specific amiibo is an exclusive to the retailer in the United States. You will be able to get hold of the Dark Pit amiibo on July 31st, but you will only be able to purchase it at your local Best Buy store. You can’t pre-order the Dark Pit amiibo. So yeah, sounds like you are going to need to queue.
