Items you pre-order are reserved for you, and will be shipped out as soon as they are available. You can find the estimated shipping date in the item page and in your order details.
If you order products that are already in stock together with pre-order items, they will be shipped in separate packages.
The total of the pre-order items will be charged on your chosen payment method after you order in placed. Cash on delivery is not available for pre-order items.
