Before everyone gets all excited, there's a $5k limit per person on I bonds. Great return, but just a low limit. It's easy to look up all the details, just do a google search.
I've got 30K of my own cash in it this year, 10K for myself, 10K gift to my wife, and 10K gift to my kid. I wish I had my own trust or LLC to buy for.
It's 100% 10K.Its 10K per person annually and you can also use up to 5K from your tax return. At least I hope its 10K, I opened an account yesterday and placed an order!
