I've used Treasury Direct to cash in savings bonds, but the website is difficult to use. Login page uses a virtual keyboard to enter password and my clicks sometimes register nothing and sometimes duplicate entries. Site does not allow display of password to verify entries. Takes me multiple tries to get in. Once I'm in, an error (?) navigating from one page to another kicks me out my account & requires another login. Wish they would allow password display on login and kick me back to your account page instead of out the website completely. Worst website I've ever used.
