Discover and Apple Pay Reminder
If you have an iPhone 6 or newer, you should probably take advantage of the Apple Pay/Discover deal. Extra 10% reward back when you use Apple Pay till the end of the year (up to $10k). All your rewards will double for a year (basically 2% everything, even non-Apple Pay). So potentially you can get 22% back anything you pay with Apple Pay and 30% back at department stores that take Apple Pay (e.g. Macy's). This is a great deal, especially with the holidays coming around.
For the electronic geeks, most Best Buy are starting to accept Apple Pay.
I suspect Android Pay will have a similar deal in the near future, but I'm not sure. If you have any questions, just ask!
Here's a link that will get you and me $50 (possibly $100 if the rewards double, which I think they do) if you sign up.
