I got a US Bank Cash+ card a few years back as a product change from my second Flexperks Travel Rewards card. Back then the Cash+ had a somewhat more lucrative earning structure, offering a $25 prepaid Visa card as a bonus whenever you redeemed $100 or more into a US Bank savings or checking account. They've since eliminated that bonus, but I nonetheless recently dusted off my Cash+ and began to use it as another uncapped 2% cash back card at grocery stores.
Yesterday I noticed that the link had appeared in my US Bank online account to select my Cash+ bonus categories for the first quarter of 2016. I don't see any major changes to the available categories this quarter, so I plan to select "Grocery Stores" as my uncapped 2% cash back category, and "Charity" and "Department Stores" as my 5% cash back categories (capped at $2,000 in quarterly bonus spend).
If you're planning to buy any new Apple devices in the first quarter of 2016, be aware that the Apple Store does count as an "Electronics Store," and I may decide at the last minute to select that category instead since it's relatively difficult to find big discounts on Apple hardware.
US Bank says it takes a few days for enrollment to take effect, so you'll want to select your bonus categories now, before you forget.
