The full story

You didn't want the large size until you saw the medium. That middle option wasn't built to sell. It's an engineered trap designed to steal your cash. Psychologists call this the decoy effect, and retailers use it everywhere to quietly dictate your choices. Imagine a small coffee costs $3, and a large costs $7. Most people pick the $3 cup.

Now, the menu adds a medium for $6.50. Suddenly, the $7 large feels like an absolute bargain. But here's the part nobody mentions. The company never expected anyone to buy that $6.50 medium. It exists purely to frame the large. By comparing $6.50 to $7, your brain forgets you just spent $4 more than you needed.

Small leaks add up fast. A $5/day habit totals $1,825 a year out of your pocket. Invested monthly at 8% for 30 years, that money grows to $226,659 instead of vanishing. STEP ONE to beat it: ignore the middle price entirely and decide your purchase before you order. Follow for the money rules school never taught you.

Because you never really wanted the large size until you saw the medium.
