The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.
