Please check your order confirmation email for the stock availability message of the item. If it has a "Usually ships..." message, it will be shipped out to you at a later date within that time period. For example:
In other words, for orders that contain both "In Stock" and "Ships at a later date" items - we ship out the "In Stock" items immediately and send out a later shipment for the remaining items.
If the item that is missing from your order is "In Stock" - please email us at email@example.com with your order number and the item/s that is/are missing from your order. We'll start an investigation with the Warehouse orders fulfillment team as soon as we receive your email.
