Has to be used for grocery or convenience store, not restaurants. I use the credits for pick-up orders at 7-11 or Maverik. I make two separate orders back to back and then go pick up both at the same time. I usually just get candy and beef jerky.
The $5 credit has already been a perk but it might be changing. It would carry over for 2 months so you could have $15 to use on the third month. Now, it might just be $5 a month (use it or lose it at the end of the month). It's $5 off any restaurant order.
I also hate that they got rid of the airport restaurants.
