Seriously,
free next day delivery (order up to 8pm or something)
texted time slots on the morning of the delivery
emailing you the name of the delivery driver!
options by text eg deliver to neighbour
100% reliable
AIBU to ask If they can do it why can't any other companies?
I've got the free Amazon Prime offer at the moment and more often than not (when stuff is actually eligible) it turns up about 8pm just as I'm doing bedtime, having waited in all day.
