I just start to pay attentions to I Bonds as cash part.
May I ask what's the best way to buy I Bonds? at www.treasurydirect.gov? or local banks? or Fidelity, Vangaurd?

thanks in advance.

just got the book. still digesting. one question for Craig/J.M.: on chapter 3 about performance of the PP: Table 3.1 returns were resulted from rebalancing to 25%/each yearly or when 15/35 band hit? if they're yearly rebalancing, what is the returns for 15/35 rebalancing? I assume this maybe alread...

did anyone actually sell T-Bills/Bonds at Schwab online and no fee?
I haven't, but did both online chat and email confirming that you can't sell them online yourselves therefore you need to call for that, thus incurring charge of $25 for phone assistance.

Thanks Craig, for such quick reply.
would the returns from 15/35 rebalancing better than yearly one?
