I just came across this Savings Bond Advisory:

Given that the current fixed base rate is 1.20%, it would much better to invest in I bonds this month rather than waiting until May 1 or later. I bonds you purchase today will earn a composite rate of 4.28% for six months, followed by six month of 6.06%. These are much higher rates than are available in bank CDs or even other US Treasury securities.

I should also add, this is better than any online money market rate, 6-month CD or 1-year CD you can get anywhere these days. There is a purchase limit though:

Also keep in mind that the Treasury changed the annual purchase limit on Savings Bonds in January to $5,000 per social security number per type of bond. This means you can invest $5,000 in paper I bonds at a bank and another $5,000 in electronic I bonds through Treasury Direct for a total of $10,000 per social security number.

Or, you can buy up to $5,000 gift bond for each member of your family (spouse, children) who has a valid SSN.

Sounds good to me - what about you?
