Back in July I applied for NASA membership because I was entertaining the idea of getting one of their credit cards and part of the application had me enter a credit card so that I could fund my share savings account. The card never got charged and I assumed it's because they are slow in doing things until I got a letter saying they closed my savings account since I didn't fund it within 30 days of joining. I debated if I should reopen my account but decided not to, they are just too clunky and I am spoiled with the online portals of my Discover, Amex etc I am still a huge fan of CU's and I plan to approach PenFed next September, hopefully that will turn out better.
Honestly, they did you a favor.
Some members have had good luck and it is a SP (or at least was) to join and apply for a CC.
Other members have only been able to get the non-credit accounts opened. I have a savings account hidden away with NASA that has a direct deposit, so for the time being I will just leave it slowly grow. When it comes down to closing accounts they are number one on my radar. Just my 2 cents.
Of course it is your choice, but NASA can be difficult. I think I am the last poster here on MF(from what I have read.) that had an easy SP for both membership and 29.7 CL. I also deposit automatically monthly into a savings account there. The Rewards card is one of my daily drivers. I remember when I applied a year ago that I was asked how I found out about the credit union. A little voice in my head told me that they followed the MF boards and there was a lot of posting about them then. Just my take.
