Instead of items displaying as "SOLD OUT/BACKORDER" for example, the website is set up that when "IN STOCK" items sell out, the product page and listing automatically changes from "IN STOCK" to "PRE-ORDER" for every item on the site, regardless of whether or not the product can actually be ordered/sourced on their end again or not. You can see this with the numerous Funko Pops for example on the site all displaying "PRE-ORDER" although the pop was released a number of years ago and now vaulted (no longer manufactured/sold). This is why so so many people complain about pre-orders being cancelled on this online store, because it's only once enough people "pre-order" actual sold out and unavailable items like these and the site cancels their orders that the people running the site then go ahead and remove the product from the website. It's deceitful and lazy online inventory management.
