If you are eligible to join this credit union, you may be able to get this CD rate up to 5.50%. The credit union has a point system in which you can earn points for several types of activities. The points can then be redeemed for a lower loan rate or a higher certificate of deposit rate. For example, you can earn 100 points when you register for and use Bill Pay. But it takes a lot of points to get better CD rates. You need 2500 points to get a 0.25% higher CD and 5000 points to get the extra 0.50%.
