yeiks. i have never purchased any regular savings bonds, but have purchased I bonds. Those are simply purchased thru a bank. I bought a $5,000 I bond 2 years ago... had no issues what so ever. All my other bonds are Inherited, so all i had to do is re-issue them in my name.
Personally im happy with the interest the I bonds and the EE series bonds have made. The older ones i inherited are currently earning between 4.0 and 6.28% per year...depending on issue date. The newer I bonds vary between 3.89 and 4.6%.
Compared to 0.25% that Wells Fargo offers, bonds are great
