For anyone who's still following, here was my timeline:
April 30: Applied online with credit card info, using Chase AARP card for 1% cash back, uploaded scan of driver license
May 6: Received an email with a document to e-sign, account is opened, credit card gets charged (as a purchase, not a cash advance).
...
December 6: Reminder to opt out of CD being renewed!
I absolutely don't understand how it makes business sense for them to allow credit card funding, but I'm not complaining. Thanks for the free $350+, NRLFCU!
