It’s not possible for us to guarantee delivery times. There are many factors that can cause a delivery delay- equipment breakdowns, natural disasters, strikes, customs delays, and other unforeseen circumstances can delay your package. If you expect that you may not be home to receive your package we strongly encourage you to use the UPS MyChoice Service to schedule your delivery or to direct your package to a UPS Access Point near you so that you may pick it up at your convenience. To use UPS MyChoice Service visit the tracking link for your shipment, then click the Change My Delivery button in the lower left corner of the tracking information.
