"Get couriers to deliver to a nominated supermarket"
At least one courier (DPD?) in the UK has a network of shops which will can be used like this - get your parcel delivered to the shop, and pick it up later. They are "useful" shops too, in that they are open in the evenings. My local Sainsbury's was on the list when I looked into using it.
A co-worker has used it successfully once, but was put off when he was able to collect a parcel by walking up to the Customer Service counter and saying "I'm here to pick up a parcel". He was given the parcel with no ID check, and no requirement to sign for it.
I didn't risk using it, and opted to wait in all day on a Saturday.
