Didn't intend to get a Playstation 5 but was helping friend monitor the playstation 5 preorder. Below was what I observed.
At 10.59am, Sony online store listed the PS5 for sale. The page showed sold out at 11.01am.
Very briefly after 11am, Toys and Games listed the items for $50 preorder on their website. It was sold out within a few minutes.
Courts listed the items at 11.13am. The issue with Courts' listing was that you have to use specific search words. If you use the term "Playstation 5", it won't show up. You have to use terms "Playstation-5" or "Playstation+5".
Plenty of stock until someone here posted the link online at 11.30am. From then, it was sold out within 10 minutes. I saw a brief display "50 sets left" on the disc edition at 11.30am, so it probably meant at least 50 sets were available.
Harvey Norman also listed the items briefly for sale, but I wasn't sure when it started listing it. When I checked at 11.40am, the disc edition was sold out, and "45 people bought this today" was displayed. The digital edition came back in stock at 11.50am, then was out of stock in an instant. Shortly after, the item pages were brought down. I stopped monitoring after this.
Hachi.tech listed theirs late and someone posted the link here.
Didn't see Best Denki, Gain City listed any for preorder.
Didn't monitor Qisahn or Play-E store.
