I have heard a lot of good things about PenFed so I finally decided to join them on Friday. I opened up a savings account with them in order to become a member with them and I have my eye on this card of theirs.

It's called the Visa Platinum Cash Rewards card and it gives you 5% cashback on gas purchases when you pay at the pump, 2% on supermarket purchases, and 1.25% on all other purchases. I don't think it has a cap on cashback. I applied for it yesterday knowing that I was going to get denied because they pull EQ and I just finished paying off my most of my debt. I also have a lot of inquiries on EX but not EQ and have a lot of new accounts. I checked the status of my application yesterday and was denied. I am waiting for the letter to see what the reasons were so I'll know what to expect next time I apply.
