Sometimes, we just cannot wait to show you our newest products. So we give you a little peek (and let you order it early, before it is in stock at our warehouse). When you purchase an item, we will ship it out to you within one to two business days after it is available at our warehouse. You can see if you are buying an item that is a Pre-Order item on both the product description page:

The Ship-On date below is an estimate of when we expect to ship your items after we receive the product from our factories. After you’ve placed your order, we’ll send you a shipping confirmation email once the item leaves our warehouse. Please note you’ll be charged for the pre-ordered item at the time your place the order.
