This is RFD. Any time there's an error in our favour, a bunch of members will notify a CSR/Supervisor/Manager, often providing a link to the very thread and post outlining the error.
"Is this price error order going to get cancelled?"
"Everybody else on RFD got it at this price error price, can I get it too?"
"This price error order is taking too long to ship, when are you going to ship my price error order?"
"No, I'm not making this offer up, here's the thread on RFD with a bunch of anonymous people on the internet discussing it. See, proof!"
