I think they put in an order early from their Plarail suppliers for x amount to initially have in stock. Don't know if they have the same number every time or try to judge how many to have when the item is released. For most Pre-Orders you pretty much have to be there in the first few hours before all that they have coming are spoken for but it is First Come First Served.. Then once the initial shipment comes in and they satisfy to pre-orders they order more. So I think they will have them in after their release. If you click the 'Notify When Available' button they Email you when they are back in stock so you can buy them then but you aren't obligated to so it doesn't hurt clicking that.
