Amazon Logistics in the UK shit all over the other carriers Amazon used before that from a great height. Sunday delivery, quick comebacks if you're out, intelligent storage of low value parcels if you're unavailable, actually leaving cards reliably etc.
I am super glad Amazon started using them instead of fucking Yodel.
Yup, they're fantastic. Don't know if it's the same for the rest of the UK, but in London the drivers seem to have their own dedicated areas rather than a rotation, so they get to know customers, e.g. which neighbours to leave stuff with, if you don't mind stuff left by your side door etc.
Amazon is one of those companies that really make you realise how complacent others are. Aside from FedEx and a bike courier we sometimes use, all the other firms seem awful - haven't changed at all in 20 years aside from text messages, like to pretend getting a message to the driver is harder than contacting the ISS, etc.
Now, if they could just improve their employment issues...
