Here's a rare example of one done right: http://www.tf2outpost.com/trade/9494763
1. person actually sold keys at the listed price and promptly
2. restrictions imposed were fair and given upfront
3. trade was closed when the keys were gone.

When I want uninformed economic theories, I go to bp.tf. I come to outpost for trading and I'd like to see fewer stupid forum posts disguised as trades.
