Someone I vaguely know has listed an item on a local group as 'up for grabs, on its last legs be quick'. I would be able to use the item, so PMed them to arrange to collect it. All good. However they've asked me to drop cash through their letterbox, if I feel like it, or just take it if now. I was expecting it to be free but now feel awkward just taking it. AIBU or are they?
We wouldn't otherwise be going to buy this, and the price they've asked for is only a little less that it would cost if I'd bought it new (rather than collecting something which is 'on its last legs').
