  • Younger sister bought a $28k car with a 84 year loan and 7.99% interest
    Investigate immediate refinance Loans from different credit unions ( penfed.org, etc). Credit Union pays off that loan and reissues a different loan, less predatory Interest rates, more favorable terms and conditions. Source: over 3 years ago
  • Refinancing options
    I would try credit unions in your area or even out-of-state credit unions that are easy to join by everyone. For example, a quick search shows that penfed.org has 5.04% for a 60-months loan. Source: over 3 years ago
  • [AmA Alert!] Hey all! We're Dashlane's Autofill team and this is our AmA! Ask us anything!
    OK we took a quick look at penfed.org and it looks like this site is using some technology (namely "Shadow DOM") that we don't yet fully support for manual correction. This is why your changes are not persisting. So it will take longer... Source: almost 4 years ago
