Yup , last year i I payed 300$ for my pro tools 9, and they give you 4 years of free upgrades.
dope. You can also get plugins at student discounts. Fabfilter offers a 50%student discount. Soundtoys also offers a discount. I think also at 50%.
Waves offers 35%discount on some bundles. Avid also does discounts on them. BUT UNFORTUNATELY NATIVE INSTRUMENTS. DOES NOT. :/ unless your a school.
That's all I've looked into myself ...
Or you can use the pay as you play option at zZounds.com I've used it for maschine I'm so tempted to do it again for komplete 8 ultimate.
