When I first posted about AFCU on May 23rd, they were offering a 6% 6-month CD along with the 6.36% 36-Month CD. Last Thursday, AFCU ended that 6% 6-month CD special but retained the 6.36% 3-year CD.
AFCU has an easy field of membership that allows anyone to join via membership in a non-profit organization. Refer to this post for more info.
Another note regarding AFCU is they have an online banking system which allows you to apply for membership and fund an account. Also, you can fund new accounts with a credit card. Many on this FW thread have reported that they've successfully funded a CD with their cash back credit card and it was treated as a purchase and not a cash advance. Thus, it wasn't charged interest/fees and was eligible for the cash back bonus. However, some have reported that it was treated as a cash advance. Another thing to note regarding these CDs is that you can't transfer more than $10K from a newly linked funding account.
