I had a similar issue getting my hands on a particular configuration of the Latitude E6xxx without Windows preloaded. I spoke on the phone with customer service (as a small business) and in the end they agreed to apply a discount of $80 (the price of Windows 7 OEM on newegg) to the notebook. I'll admit it made the order process a little more frustrating that it had to be, but it's much better than trying to get a Windows refund after you make the purchase!
Dell will pre-refund Windows
