I got an email a few days ago with a holiday promotion: 10x miles on gas, 5x miles on Amazon purchases and groceries from 10/1 through 12/31. I got it for my Quest card but not the Explorer card.

I also noticed that when I look on Chase, the 10x miles shows up for a gas purchase I made, but the 5x doesn't show up for some grocery purchases. Is this just a Chase.com glitch, or should I actually worry about this? I'm guessing they'll credit properly when each statement closes?
