I just got a targeted email from CapitalOne.
"For a limited time, your Savor card will earn you 4% cash back on every purchase, every day.
It doesn't matter if it's groceries, shopping, dining or entertainment. It's 4% on everything. The only limit is your imagination. No hoops to jump through. Just use your Savor card.
Today until December 31, 2019
After that, you'll earn the rewards you're used to: 4% cash back on dining and entertainment, 2% at grocery stores, and 1% on all other purchases—just like you always have.*"
So check your emails if you have this card.
