Good to hear that Christmas orders are (mostly) turning out okay.
It used to be quite common for me to be phoned by an Ocado driver a couple of hours early if he was delivering locally (which is much nicer than waiting up for a late delivery). I'm not sure whether this is because I have a delivery comment "It is usually okay to deliver early".
I've taken in a neighbour's shopping once (often comment that the entire street should coordinate our deliveries) but I would have been cross to arrive home to find my shopping left early if they'd not phoned to check.
