Some credit unions offer good credit card deals. In addition to the well-known PenFed, there's Lake Michigan Credit Union which has a credit card called Max Rewards Visa Credit Card with the following cash back features:
- 3% cash back on gas purchases (up to $500 per month) or three Reward points on gas purchases.
- 2% cash back on all grocery purchases (unlimited) or two Reward Points on all grocery purchases.
- 1% cash back on all other purchases (unlimited) or one Reward Point on all other purchases.
