Chase's Amazon Cashback Card
If you buy much of anything on Amazon and already have Prime, this is the no-fee default: a flat 5% back at Amazon, Whole Foods, and even bookings through Chase Travel. The rest of the categories are fine (2% on dining, gas, and local transit including rideshare), but the real value is stacking everyday Amazon orders at 5% without thinking.
If you don't have Prime or rarely use Amazon, skip it—without Prime you're looking at the 3% Amazon Visa instead, and there are better general-spend options. Do the honest math on Prime itself, too: at $139/year, 5% only beats a plain 2% card once you're spending north of about $4,600 a year on Amazon. Bottom line: Prime members who shop Amazon monthly will squeeze easy, reliable value here.
