So after waiting several weeks (before I posted this), I actually had some time to talk to a sales person on chat and he stated that the coupon was maxed out!  Why has Dell been falsely advertising a coupon for over 2 weeks when no one can use it?  I think I'll shop elsewhere from now on.
Last week I attempted to use coupon VPJ1MHN3Z6T6V3 for an alienware alpha, however at checkout the system stated that the coupon is not longer valid.  If that is the case then why is it displayed over 4 times throughout the dell.com site up to and including checkout, as available to use?  The computer I wanted was the 799.99 alpha with an external dvd drive.
Why show a coupon available if you cannot use it?
