The Blizzard Gear Store is directly from Blizzard.
And Blizzard Gear has out of stock. WoW Website says to get the Collector’s Edition on Selected Retailers. WoW Website pre-purchase button leads to Selling of Base, Heroic and Epic Edition and they are not Collector’s Edition.
Okay but I was never talking about whether or not it was in stock. I’m simply telling that user that no, there is a way to get it directly from Blizzard.
Anyway, I pre-purchase mine on Target. Their website is updated. They promised to deliver it to me by Oct 14 to Oct 19… With Oct 26 launch date, looks like I am pretty safe to be able to play on launch date.
I could show off my copy here before launch date. 
I hope Target wont fail. Amazon, Walmart and Best Buy has bogus Delivery date… Dec 31, 2020.
Since when have they not ever do a box for collectors?
Update: I pre-ordered my Collector’s Edition last month from Target. Yesterday, I received an email from Target that they started processing my pre-order. They took my payment of $129.29. Now, my package is on in-transit. They expect the package to arrive my house on 12th of October.
I am excited. I have all the Collector’s Edition of WoW… and my Collector’s Edition of Shadowlands is coming soon. /Dance.
Ditto your entire post, but replace Target with Best Buy, and $114.42.
And I am only missing Vanilla CE. 
It’s $119.99 on Bestbuy. A little higher when tax is included.
Yeah, I dont have Vanilla CE too becoz we have no idea what WoW was all about. And I didnt have a Broadband internet then. I was with dial-up. WoW was the reason I got a Broadband modem.
After my amazing adventure on Vanilla as Naxx40 raider, I started buying all its CE on Expansion.
Probably a discount for Best Buy RewardZone, since I have been a member since they launched it.
If I had known they would be battle pets, I would have tried to find one in 2005, rather than wait until the prices were well into the thousands of dollars.
