We cannot guarantee when an order will arrive. Consider any shipping or transit time offered to you by drguberman.com or other parties only as an estimate. We encourage you to order in a timely fashion to avoid delays caused by shipping or product availability.
If you order a product via priority mail or express overnight and product is not in stock we will make every effort to ship your product as soon as possible via the expedited shipping method you choose. We will be happy to refund your monies for shipping but we then will mail your package via ground at no charge to you.
