They're local prices, further research proved this.
If you live in Texas, you can craigslist them. My friend picked up a couple, $359.99+tax each from a small business (Craigslist). New and sealed of course. He called Dell to confirm that it was still in warranty and all (3 years each, starting from purchase date). Don't always have to go retail to get warranty/new :P
Also you can check Ebay out as well, many of them will guarantee or prove Dell's warranty to be good and running for 3 years. If they lie, you have paypal protecting your $ anyways.
