This is the box I'm planning on using for shipping:
I don't think it needs anymore details other than: "Fragile Perishable & this end UP" when sending FedEx Priority Overnight.
IMO best options are to mail early in the week in case a connection is missed.
If mailed on Thursday for Friday delivery, one missed connection could mean a layover until MONDAY.
(Been there & had it happen
)
There won't be any weekend deliveries unless you specifically PAY EXTRA for Saturday delivery.
Hold for pick-up at a nearby FedEx location might work better than drop off delivery also.
Just ideas....if you have any, please share.
