Contrary to the common perception of users paying off balances monthly ("transactors"), the majority—about 60%—are "revolvers" who carry debt. This group is the primary source of profit for card issuers, as they are subject to interest rates now averaging a staggering 23%.

Instead of offering direct discounts, which can devalue products, consider a double or triple loyalty point event. This strategy incentivizes customers to spend more to earn future rewards, effectively driving sales while encouraging repeat visits and fostering long-term loyalty. It costs little while giving customers a strong incentive.

For high-end brands hesitant to offer discounts, Apple's model is ideal. They sell products at full price but include a substantial gift card for future purchases. This drives sales and encourages repeat business without ever putting the core product "on sale," thus preserving brand prestige.

The business creates two offers: a high-ticket annual prepay ("anchor") and a standard quarterly payment ("core"). Even if only 20% of customers take the anchor, it significantly increases the average cash collected per sale across all customers. This strategy makes the entire acquisition model more profitable without changing the core product.

Instead of a generic '20% off' coupon, framing a promotion as pre-existing store credit (e.g., 'You have $21.63 in credit expiring soon') is more effective. This psychological trick makes customers feel they are losing something they already own, creating a powerful motivation to buy.

A surprisingly large portion of high credit card APRs covers operating expenses, particularly marketing. Issuers like Amex and Capital One spend billions annually on customer acquisition. This spending is passed directly to consumers, as higher marketing budgets correlate with higher chargeable rates.

The math behind a high-ticket offer is often misunderstood. Since these services are typically 100% margin, a small number of buyers can drastically outperform the profit from your main product. A 10x priced offer sold to just 10% of customers can double revenue and triple profits.

Early-stage businesses can strategically leverage the 30-day interest-free period on credit cards as working capital. By ensuring customer acquisition costs are recouped within that window, your credit limit effectively becomes your advertising budget without incurring interest or debt.

The system of charging retailers an interchange fee (around 1.8%) that is then passed to consumers as rewards (around 1.57%) creates a strong network effect. Consumers are incentivized to use rewards cards, and retailers cannot easily offer discounts for other payment methods, locking both parties into the ecosystem.
