Just a mention for the subject CD. The jumbo version is yielding 4.9% APY. Jumbos start at US$25K. Below that the yield is lower.
Some things to consider:
Alliant allows members to name the DAY of maturity for this Share Certificate. It's a really nice feature, and allows depositors to avoid having the certificate mature on a weekend.
This certificate pays interest monthly but you CANNOT withdraw the interest. The interest is declared and paid into the account and it compounds . . . but nothing is permitted to be withdrawn until your certificate matures. So this instrument is worthless to you if you need, for example, monthly income.
You cannot open this on-line regardless it appears possible when you visit the Alliant web site. You must download the new member application and download the share certificate application, fill both out following the instructions, and send them in with your check. There are also other less favorable funding options, which I did not use.
Finally, membership is straightforward. Just join your local PTA or PTO and you qualify. You can also join the NATIONAL PTA but that costs $25. For me to join my local PTO cost exactly $1.
Here's a link to the Alliant web site to get you started:
