There are a lot of sought-after items that are in short supply due to this global chip shortage. The Sony PS5 and Xbox are prime examples of this. They launched back during a high point in the Coronavirus pandemic to boot, so that didn’t help the situation. A year and a half later, and the situation hasn’t changed much. When more stock for that item comes in, the user will then get an email reading that they’re invited. According to the screenshot posted, it looks like the users will have a 72-house window to purchase the item. We’re not sure if that’s specific to the item or not. When the user gets the email, they can then go to the page and purchase the item as usual.
