While you are buying your discounted 2011-12 ski season pass, don't forget to buy season pass insurance offered with the pass. It's an additional $20 but it's well worth it if you can't use the pass due to health reasons during the ski season.
Most ski resorts offer season pass insurance during their annual pass sales period. Don't ignore it. If you get hurt or have health problems - the resorts are not going to reimburse you for your pass unless you purchased pass insurance.
Don't be penny-wise and pound foolish - buy the insurance. Have an avenue to getting some of your money back. Even discount passes cost a chunk of change.
