A long term suggestion that won't tie-up all you money at once, is to spread out your purchases. Instead of buying, lets say, $24,000 of savings bonds at once, is to buy $2,000 per month. That way you'll always have some bonds you can cash in any given month (after the required holding period).

This process is commonly called laddering.
