We are not able to start accepting preorders for an item until we receive official information about it from its manufacturer.
Preorders for an item might start at any time of day or night. We're afraid it is not possible to predict a specific date or time. We also do not have a service to alert you when preorders have begun.
If you'd like to know if we plan to accept preorders for a certain item that isn't already in our online catalog, you are welcome to contact us.
