The $50 buys you a voucher which is good for apx 1 year (after 12/14/13 it becomes worth $50). However your one year membership doesn't begin until you actually visit and redeem the voucher. So you can buy now and the 1 year clock won't start ticking until you go the first time.
Not sure if this is tax deductible since it is purchased through Amazon. I guess that one is YMMV through your accountant.
