Yes, our system does not allow any orders to be placed on items with zero quantity, however, because we are a marketplace we can only confirm that our stock quantities match what the seller has listed.
There may be times that they add stock for a pre-order item, however, we try to avoid that and it usually is clear within the listing that this is a pre-order item with an expected shipping date.
If you wish to confirm this question before ordering, please reach out to the seller directly with the "Ask A Question" button on the product or their store profile.
