The availability is a lead time before the items ordered will be shipped out. So if you order an item with an availability of “Ships within 3-5 Days” your order won’t ship until the item arrives into our warehouse, which can take 3-5 business days.
If you place an order with a mix of product availabilities, then your order will hold until it is complete, unless you request a partial shipment. If you request a partial shipment then we will upgrade your shipping cost appropriately. If you paid $11.75 for 3-Day Delivery and you wanted us to do two shipments, then we would charge you an extra $11.75 to send the additional package.
