JCNA Member Discount F-Type Coupe

I was prepared to pick up my ordered F-Type Coupe R this week, but the dealer sold if from underneath me before I could close the transaction. I know have to order a new F-Type Coupe from the 2016 allocation, with an expected delivery in March or April 2016. I had planned to use the $2,500 JCNA member discount this month, but alas, that will now be impossible. Do you know when the offer will expire?

Thank you.
