Saturday is considered a business day for UPS shipping, but only for time-critical shipments. Regular orders are delivered Monday through Friday, and any item delivered on a Saturday must have a "Saturday Delivery" sticker on the package.
UPS has a range of domestic and international shipping options for Saturday deliveries. For example, UPS Next Day Air Early A.M. guarantees delivery 1 hour later than weekday delivery times. International delivery times depend on the destination. For some Saturday services, the delivery of a UPS return shipment is only permitted within the United States. Contact a local UPS representative for detailed information regarding Saturday UPS deliveries in specific areas.
