Which card

Which card is best for groceries, and why does the answer change mid-year?

The highest grocery rate is not the best grocery card for most people. Published rates, the caps that end them, and the break-even that decides the fee.

Which credit card should I use for this purchase?

Four facts decide which card to reach for, and three are printed on the issuer's page. The order to check them in, worked through on real published rates.
