Imagine this: you order a new pair of jeans and a pack of Percy Pigs. Instead of chasing a delivery van, you head to your local M&S. You walk in, grab your bag, and suddenly you’re tempted by a gorgeous cashmere jumper on the way out.
That’s the sneaky genius of it. M&S knows you’ll buy something else. It’s like a friendly trap, but you love it. You came for one thing, and you leave with a full shopping bag and a smile.
