it takes two. i've seen some posts where the sellers don't define the terms nor stick to them, that's unfair to buyers/ bidders. there are also instances where buyers back out at the last minute and do not honour the deal by not meeting up - i think those also deserve to be shot because they've no respect for the sellers who make the time and trouble to meet them, with the goods. still, its not as bad as ebay where you can't actually see/ feel/ test the product before you complete the transaction.
