If it is grocery cashback that you are thinking about, don't shy away from the Blue Cash Preferred. The 6.5k at 0.50% vs 5% = a lost 6.5k * 4.5% = $292, which far exceeds the $75 annual fee of the BCP.

Of course, the BCP 6% is for grocery stores, and not for drugstores, so if you specifically have huge charges at Walgreens, then the BCP might not be the appropriate card to charge to.
