Just placed an order for one of these using the same trick for the Deal Alert for the Nokia DT-900 that just got posted here.
Deal alert: Nokia DT-900 wireless charging plate for $12 shipped | Windows Phone Central
Just follow the instructions listed, but instead of picking a L920, pick a L1520 and select the Incipio Ghost Charging case. Thought I should post, in case some L1520 owners disregarded the Deal Alert, thinking it was just for the Nokia DT 900. In fact, the deal is just an exploit of the Microsoft employee discount on accessories purchased at AT&T (50% off most non-Apple branded accessories) and works for 50% off of a lot of cool accessories. Even saw an iPhone 5 Mophie Juice Pack Helium for $40.
Edit: I did receive a confirmation email, but status of order is still pending confirmation. Hopefully I get it... and soon.
