Saving is the way to bet on deflation. If you really want to bet on deflation simply sell all non-necessary assets now, hold your wealth in cash or 10 year T-bills (not short-term interest bearing debt which are highly-correlated to the rate of deflation), and watch your cash/bonds appreciate relative to the goods you've sold.
