Buy now, pay later:
the quarter-price illusion.

Klarna's greatest trick isn't credit. It's typography: showing you "£30.00 × 4" in a font that makes a £120 jacket feel like a £30 one. Buy now, pay later isn't evil — it's just a machine for making prices feel a quarter of their size, installed at the exact moment you're deciding.

What splitting does to your brain

Paying hurts — measurably, researchers call it the "pain of paying" — and that pain is a feature. It's the price tag's honest handshake with your budget. BNPL anaesthetises it: the first instalment is painless, the jacket is already yours, and the remaining £90 becomes Future You's problem. Future You, famously, did not agree to this.

Where it compounds
