You have to remember that the sticks are in cello, in a bag, in a box and are stored at the vendor quite wet to lessen the chance of damage during shipment. Unless they are exposed to extremely low RH just sitting out for 4 or 5 days, I would not fret over a few extra days in transit. I've stored sticks naked in a ziploc bag on a shelf for months at a time with no ill effects.
