If you go to a product page like: https://www.bestbuy.com/site/apple-iphone-11-pro-max-64gb-space-gray-at-t/6341313.p?skuId=6341313
You'll see a little "Help" blue box pop up on the right side of the screen. From there you can select "Chat with us" and then a new pop up window will open with a bot. At the bottom of that window there is "Live Chat" which will take you to a real person. Let us know if you get different information!
Thanks, I got the same response. Delivery 9/20 end of day or 9/21 since I pre-ordered.
