There's an item on ebay I'd like to get, but it's pick-up only. The seller has said they'll accept courier pick-up - how do I arrange this, if I win? Do I ask the seller to pack it appropriately, or will the courier do this? I'm guessing there'd be a fair amount of correspondence between me and the seller over weight, dimensions, when to pick up, etc. Anyone done this? Apologies for what's really, I'm sure, a pretty daft question...
