I work for the Post office. I've been around UPS all my life and my father is retired from them. The USPS is getting quite a bit of QVC volume and it isn't just the lite weight items either. The USPS is really pushing sales to increase volume. The extra day (Sat) is a benefit they offer. No extra charge for Saturday delivery. Give the Post Officetime though. Mis deliveries and lost packages with horrible scanning and UPS will get it back. The USPS is really cutting the time in transit by putting these items on Fed Ex flights.
