Customers have occasionally been disappointed in USPS Ground.  USPS is most convenient as they pickup here automatically every day.  If you prefer USPS Priority or FedEx please contact us BEFORE you place the order.  We may do the upgrade at no charge or bill you the difference later.  We want you happy with your order.
