I think it varies a lot from location to location. UPS is very dependable here M-F. On Saturday they've never completely missed the delivery or delayed it till Monday but it often is after noon when it arrives on Sat. M-F it's usually here by 9-9:30. Fed Ex is ok but not great. Haven't used them for a Sat delivery. USPS is pitiful here. Only livestock I've ever lost because of shipping issues has been from them.
