Be warned! I am going to tell you about the Pentagon Federal Credit Union credit card scam that many are falling for including myself! I applied for the Penfed credit card for the same reasons others do and that is the supposed rewards it offers. What they don't tell you though are the costs you will have to pay to get those awards and how unethical the company is with issuing credit.
I have a flawless credit history of years with not a single late payment, no debt and credit lines in the tens of thousands on three of my cards. But be warned! The one thing I did not have was an installment loan like a mortgage. The heavily weigh this in their credit score. If you don't have one they don't care how good your credit history is. They will either not issue you any credit or issue an extremely low amount. Unless you have a mortgage you might not get a Penfed credit card or auto loan. They would rather you have a risky subprime mortgage that you're underwater on than have responsible credit history.
If that was not bad enough your Penfed credit card starts accruing interest almost immediately! With a grace period of only 10 days by the time it's printing and mailed to you you will probably have one or two days at most to pay your bill and have the payment clear. Good luck with that! They do this so they can slap you with interest and late fees easily. They reel you in with the rewards and then use it to impose unfair credit card practices so they can nickel and dime you to death!
On top of that to get the card you are forced to make a "donation" to their foundation. They claim its not profit but are there administrative overhead and salaries paid to you know who?
Be warned! Pentagon Federal credit card is a for profit scam. Stay away!
