As BigBertha says, most communities will do the right thing and take in parcels. However, as plenty have said, there is a sad sunset of people, thoughtless and/or selfish, who expect you to become a courier too.
These days this topic is made more complex because not all couriers do leave a card, though the various online delivery monitors tend to say that it's been delivered . . .somewhere!
Our village has a steady stream of people appealing for help to locate their parcel -- showing a plaintive picture of the bottom of somebody's front door with a parcel placed there. Or the similar "where does Mrs Blodgit live, I've got her parcel which was addressed here, but she doesn't live here" ones?!
Couriers are expected to deliver about a million a day, so will leave things somewhere, anywhere, take one of those daft pictures (WHAT USE is the picture of the bottom of a door -- sometimes with a pair of feet in shot??) - and whizz off in a few seconds. We've caught RM Parcels putting a 'not in' card through the door when they didn't ring and we were both in!
Some weeks back, a large item was left by the village hall door, a roll of material (over £100 apparently). We took it home, told the vendor that the process had gone wrong, the postcode was correct for the village hall, but the rest of the address was somewhere 10 miles away, no such roads in the village (the label postcode was one character out). They arranged to get it collected, I even heard from the courier firm they selected to do that (not the original one, who'd just dumped it despite most of the address being all wrong). The collection never happened, and a couple of days later a further (replacement) item turned up at the Hall (!!), this time taken in by the hirer that day. Exactly the same incorrect label. About 2 weeks later a van did turn up to collect two rolls of material, though I came within a whisker of selling them! (as compensation for half a dozen phone calls and about 20 emails!).
