Buy now, pay later services like Affirm, Klarna, and Afterpay have exploded in popularity during major shopping events like Amazon Prime Day. These services split purchases into installments, often with zero interest for the first few months. The appeal is clear: spend more today, worry about payments later.

But this convenience masks real financial risks, especially when shopping during sales events designed to trigger impulse buying.

First, BNPL services obscure true affordability. You might not qualify for a credit card because lenders consider you higher risk. BNPL companies often skip hard credit checks, letting you borrow beyond your actual means. Just because you can split a $400 purchase into four $100 payments doesn't mean you can afford it.

Second, interest rates kick in fast. Many BNPL deals offer zero percent for three to six months. After that window closes, rates jump to 20 to 30 percent if any balance remains. Missing even one payment triggers penalty fees and immediate interest charges.

Third, BNPL purchases aren't protected like credit card buys. Credit cards offer fraud protection, dispute resolution, and chargeback rights under federal law. BNPL transactions typically lack these safeguards, leaving you vulnerable if merchandise arrives damaged or never shows up.

Fourth, BNPL debt doesn't help your credit score and may hurt it. Credit card payments build credit history. BNPL payments mostly stay hidden from credit bureaus, so responsible use doesn't improve your score. Meanwhile, delinquencies get reported to collection agencies, damaging your credit when missed payments pile up.

Prime Day specifically targets excitement and urgency. Shoppers feel pressure to act fast on "limited-time" deals. BNPL marketing plays into this psychology by removing the immediate pain of payment. You get the rush of spending without confronting
