Online Shopping

CarMax is the largest used-car retailer in the United States, with over 240 stores and a national online buying platform at carmax.com. The company offers no-haggle pricing, seven-day returns, and home delivery on used vehicles. Credit cards generally cap how much can go toward a vehicle purchase, with $1,000 to $5,000 typical limits, and the transaction codes as a vehicle dealer rather than a rewards category.
