Walmart is America's largest retailer, with millions shopping in-store and online daily. Whether you're picking up groceries, household essentials, or filling online orders, the right card can earn 2-5% back on your Walmart runs.

With the average household spending $300-500/month at Walmart, a top rewards card could earn $150-300/year in cash back. The key is matching your Walmart spending pattern — groceries vs. general merchandise vs. online — to the right bonus category.

Walmart Supercenters code as groceries for most cards, while Walmart.com orders code as online shopping. This matters for category bonus cards. Check your statement categories to optimize. Pay in full monthly — carrying interest erases any rewards benefit.
