Yep and that's buying or selling. Often I'd ask if something was still for sale and could I pick up that arvo if okay and I'd usually get:

'Sold already.' which doesn't explain why the ad is still there. Or no reply for two weeks and a 'sorry, was on holiday...'

I remember going round to a house to pick up a motherboard and they handed me a box of cords. 'Where's the actual board?'
'Oh sorry, just selling the cords and cd that came with it.'
Didn't mention that in the ad and they wanted $35 for them!! Amazing..
