I am not in UPS's camp, that's for sure, but I haven't had problems with them, other than being slow. I always think their motto is "no package delivered before its time". I have seen packages move rapidly through their system and then sit in Atlanta until their scheduled delivery date.
Heck, FedEx would deliver an early Monday (before 9:30) order by Wednesday noon at ground pricing.
