Take Casper a mattress in a box start-up. This is their offer: ‘Get America’s best-reviewed mattress, delivered to your door for free, for a 120-night trial’. This is an irresistible offer that helped Casper shake up a stale $29 billion mattress industry, taking them from zero dollars as a small start-up to over $600 million in sales in their first 4 years of business. That’s the power of an irresistible offer.
