Can't speak for all,,
But unwrap it, lookover the paper work, log it into the book,,call the customer to come and pick it up.
The shop isn't putting it out for sale,,just being a middle-man & handling the transfer.
He doesn't have to inspect it for any reason, clean it, check functioning (play with it), look up values, ect.
That's for you to do.
Maybe an hour's worth of shop time the way they figure things these days.
...About 20minutes if I was to make a cup of coffee in the middle of it.
None of the NICS or 4473 stuff is done till you get there and accept it.
Give the shop a call,,maybe it's just sitting there and someone thinks you've been notified..
