Just came across this on Unidays
15% off when you sign up for 12 months.
Normally $89.99
Requires unidays account with valid student email address.
People have mentioned paying through iTunes store using discounted iTunes gift cards , but not sure if you can stack with the Unidays code. Might be worth a try.
Mod: Unobtainable deal, see comments.
Might want to mention a Unidays account requires an educational email address (at least in my experience).
