There's alot of variables these days and it's easy to bash the carriers (I'm guilty as the next reefer) but since Covid arrived on the scene more folks are shopping online then ever before and the carriers are pummeled with shipments. BUT on the other side of that coin & I've been doing it recently, when ordering livestock I explicitly state to the shipper I want it next day 10am, some say they can only go by what shipper tells them - then I ask for guarantee policy. We HAVE to press the shippers to fulfill overnight shipments - it benefits them also as not having to replace dead animals. Again the variables are countless, I've had vendors ship standard first class mail when it was supposed to be FedEx or UPS - so they're not "angels" either. Talk to your vendor, heck build a decent rapport and you won't believe what they'll do for you. Just sayin'
