How it works
In the made-up town of Lark Lane, Dara bought four things on pay later, each in four equal parts: a shirt for 8 coins, a game for 12, headphones for 16 and a bag for 4.
Each part looks small. But the plans overlap, so their parts land in the same month.
In month four all four bills arrived together and made 10 coins, ten of Dara's twelve.
Pay later does not make anything cheaper. It only moves the paying later.
