Pre-order allows you to reserve items in advance before they sell out. Please note that pre-order items will not be shipped until, or after, the estimated shipping date listed under the product description. These dates are approximate and may be subject to change without notice. If your order includes both pre-order and in-stock items, the entire order will be shipped together once all pre-order items are available. If you would like your in-stock items to ship sooner, we recommend placing separate orders.
