Groceries, gas, and dining make up nearly 40% of the average American's credit card spending. They're also the categories where card issuers offer the richest rewards. Yet most people earn just 1-2% on these purchases.
Groceries: The 6% Opportunity
Several cards offer 6% back at U.S. supermarkets, often with a $6,000 annual cap. For a family spending $800/month on groceries, that's $480/year in rewards from a single category.
Pro tip: Buy gift cards for other retailers at the grocery store. A $100 Amazon gift card purchased at Safeway earns your grocery rate, not Amazon's lower rate. SuperPay flags these opportunities automatically.
Gas: Stacking Rotating Categories
Gas is one of the most common 5% rotating categories. In any given quarter, at least one major card offers 5% at gas stations. The key is knowing which card has the active bonus right now.
Outside of rotating quarters, dedicated gas cards offer 3-5% year-round. SuperPay tracks all active bonuses and quarterly activations so you never miss a cycle.
Dining: The Competitive Frontier
Dining rewards have become the most competitive category in 2026. Several cards now offer 4% or higher on all dining, including delivery apps, bars, and cafés.
The catch? Some cards define "dining" differently. A food truck might code as dining on one network and retail on another. SuperPay's merchant intelligence knows exactly how each restaurant codes across every card in your wallet.
The Combined Impact
Optimizing just these three categories with the right cards can yield $1,200-$1,800 in annual rewards — often enough to cover multiple annual fees and still come out ahead.
SuperPay users see an average 3.2x increase in rewards earned on grocery, gas, and dining purchases within their first month of optimization.
