Sparrow Dynamics™ is a brand identity solely owned and operated by Sparrow Product Development, Inc. (aka “SPD”). The following information applies to all products SPD offers under the Sparrow Dynamics Brand (“products” or “our products”).


We will select the shipper unless a reasonable alternative is requested. We ship USPS, so we are able to ship to P.O. boxes.


Occasionally products may be on back order. If a purchased item is on back order, you will be advised accordingly. We will then ship the in-stock item, and ship the backordered item as soon as it becomes available. If applicable, shipping charges will be applied to all shipments. At this time, our website will not accept backorders. If the product is out of stock, it will not let you add the item to the cart.
