Series I Bonds...
Oh yeah, before I forget, if anyone has some extra cash to spare (and has access to the American markets), check out the US government's I Bonds; they're paying 9.62% annually - wholly inflation Batman!
One can purchase them at www.treasurydirect.gov. Sadly, one can only purchase up to $10K per calendar year. That being said, 10% percent interest is a lot better than having that money in a savings account (earning close to zero).
Cheers,
