Zvi Bodie,finance professor at Boston University, pointed out today that that with I-bonds the fixed 30-year rate of interest is still 1.2% per year (plus the actual rate of inflation), but it almost certainly will fall when it is reset on May 1. The limit per person is $5,000 in electronic form at www.treasurydirect.gov and another $5,000 per person in paper form at banks.

I-bonds are a great way to save. No credit risk. Taxes deferred until the bonds are cashed in. And you dollar is safe against the ravages of inflation.
