Orders placed after 12 PM PT on Friday are not guaranteed to be scanned in by the carrier until the following business day. Our warehouse packs orders Monday through Saturday, but carrier pickups run Monday through Friday, so a weekend order may show a tracking number before the package physically enters the carrier's network. Delivery estimates from UPS, USPS, and FedEx are calculated in business days from that first carrier scan — not from the time your order is placed.
