They need to get it together. While I understand that people are people and make mistakes, Dell is ridiculous. They have more pricing errors than any other vendor I've purchased from, and while many vendors will actually go out of their way to honor pricing mistakes, Dell just cancels your order, sometimes even after charging you the money, forcing you to wait a few days to receive a refund back to your account.
It needs to stop, and they need to get better at this. How hard is it to have one of your associates track the slickdeal and fatwallet sites to watch for potential errors like this? Then you'd only have a few hundred or so to fill, not 140,000. Somebody's got to slap them in the face with this or they'll never learn.
