Read the rest here...For those investors who prefer paper I Bonds to the electronic I Bonds issued via TreasuryDirect, and/or for those who want to increase their annual allocation from $10,000 per person, there’s still a back-door option that allows you to purchase an additional $5,000 in paper I Bonds per tax return per year.
By attaching IRS Form 8888 to their tax return, taxpayers can opt to have part or all of their tax refund (up to $5,000 per return) issued in paper I Bonds. This little-known option may well disappear at some point in the future, but the Form 8888 has been finalized for 2013 tax returns, so we know that it will be available once again this year.

P.S. I am not endorsing I Bonds as a substitute for Cash or T Bills in the PP. But for those interested this seems to be among the last ways to get paper bonds.
