Today, I noticed a surprise $11 addition to our Fidelity brokerage account. When I looked into it, I realized it was "Cash Back" from my Fidelity Amex Cash Back card. At 2%, it pays a very fair rebate. Unlike most cash back cards, they pay the rebate monthly instead of annually. If only they used a better card servicer (FIA Card Services is aweful and doesn't direct feed into Quicken), it would become our primary card.
