The packing shown by the OP would add nearly no expense.
Small flat rate box from PO free
express box from PO free
Shipping info form whatever it costs to print one page on their printer. Usually under 10 cents.
Clear pouch for the form probably also free from the PO since it was presented at the counter.(otherwise it wouldn't have the $0.00 meter)
Extra reinforced tape for using a large box instead of a small one A few cents? depends on where they buy the tape and how much they buy.
Extra labor to put the small box into the big one ==? Don't know what their shipper gets hourly but an extra 60-90 seconds can't cost much.
