If you spend thousands at grocery stores on…well, you know…the FlexPerks card is incredible. For every 20,000 points, you get another free flight up to $400. Such an underrated card for people who use it well. And now there’s a new 20,000-point bonus from Amex here. That’s in addition to the ol’ US Bank Personal and Business versions (20,000 each). If that isn’t enough, there are also the 10,000-point cards. No shortage of ways to rack up these points…
