Had to get rid of a guest bed (pine bedstead, single, with trundle underneath and 2 mattresses)
Selected an interested party who emailed their interest, gave address details, arranged a mutually convenient time, and told them I'd see them then. Also gave my mobile number in case they got lost etc.
Due to the size of the items and the cumbersomness of dragging them about, DH moved them from the shed to the front of the house about 10 minutes before she was due to collect.
She turned up pretty much on time, maybe a couple of minutes early because when I looked at the clock to see if I should "look out" for her, it was only just the time she said she'd come. Walked round to the front of the house and noticed the blue shadow one of the mattresses had been casting on our porch wasn't there anymore - then realised that she had turned up and collected them without knocking.
Okay, so I wanted her to collect the items and that is what she did, so I have no issue as such however I thought it fairly odd that someone would not knock on the door and say "hi, I'm xxx, I'm here to take the bed if that's okay?
Would you knock, or would you grab and go?
