Next day shipping for Amazon UK is pretty reliable, but I have to say I'm relived every time delivery is by someone other than "Amazon Logistics". Last time they delivered a parcel (value ~£100) I got an email saying it had been left in "my preferred safe space" (which I have never set) and had to go looking for it. Turn out they had left in my bin, at 9pm the night before the bins were due to be emptied.
