I decided to post a thread for this so people can post updates if they want to. It sold out long ago of course.
Although Best Buy's listing doesn't indicate that this is a Best Buy Exclusive, it isn't listed at any other retailer in Canada so I included "Exclusive" in the thread title.
This was supposed to be released yesterday but it is delayed. Best Buy sent out emails about it yesterday with a $10.00 eCertificate code.
Although the email says that "It will now be shipping out by September 14, 2021." that is incorrect of course since yesterday was the release date and that didn't happen.
"Thank you for your recent pre-order of a Zack Snyder's Justice League (4K Ultra HD).
We wanted to let you know that, due to continuing inventory delays, your order will take longer than expected to arrive. It will now be shipping out by September 14, 2021.
We're sorry about this, and we want you to know we're doing everything we can to get your order moving. We'll send you another email when your order has shipped.
In the meantime, to make it up to you, we’d like to offer you a $10.00 eCertificate. You can use this eCertificate amount towards the purchase of almost anything on BestBuy.ca.*
