The Mustang isn't as good as the $150 from amazon last week but it is what it is.
As far as I can see no other sets have this discount incl: 911RSR, Saturn V, Technic (discount only on Chiron), Creator, Friends, advent calendars and licensed sets.
Don't know if this is available in the warehouse.

To get the discount just following the usual shipping and payment screens all the way to confirmation screen (using any MC), you should see discount amount in the calculations before you place the order.
