Re:
To be honest, I really do think you'll be absolutely fine, as your tracking is updating at every stage, mine never got past being dropped at the parcel shop.
And to be fair to them, I have had countless items delivered by them with no problems at all. Thing is, it only takes a change of driver from a good one to a 'couldn't care less' one to ruin it all. But then again, they're all self employed from what I understand and get paid peanuts per drop, so it must be a pretty thankless job.
Not sure if they deliver actually into the evening, though I have had stuff turn up at heading towards 6pm before now.
