Interesting, thanks for the info. Living in 'the regions' in the UK I wasn't aware of those London services.

It does illustrate why in my experience non-Prime customers are drifting away from Amazon, though. They're sharpening their localised and top-tier delivery experience whilst seemingly letting 'ordinary' orders languish. Whereas I can go to another retailer, or straight to the manufacturer, and have my order on my carpet before Amazon even put it in a delivery lorry.
