I spoke too soon. Just got an update from my friend who I dropped off the boxes for.Dropped them off at Copy Copy near Casey. Zero issues.
I dropped off two 12 bottle shippers at the local Copy Copy for a friend and they accepted them no problem. Apparently FedEx picked them up at close of business that day (around 430pm) and then processed them for shipment and then flagged them (according to the tracking notice around 930pm). My friend called FedEx because of the "Delivery Exception" notice but when he talked to FedEx they assured him they would arrive on time. Today he received a call that the boxes were sent to Utah to a FedEx "research" facility for inspection and it was determined it was alcohol. He was told to put in a claim but I doubt he'll get anything out of it. It sounds like FedEx in that area is being very vigiliant about what packages get routed there.
TLDR: Zero issues dropping off shippers at local Copy Copy but FedEx is keen to shippers and will probably flag them.
