// Stacking Discounts

Two 20% discounts aren't 40% off. The second 20% applies to the already-reduced price. Two 20% discounts = 36% total discount (0.8 × 0.8 = 0.64).

// Anchor Pricing

Retailers often inflate the "original" price to make discounts look bigger. Compare the final price to competitors rather than focusing on the % off.

// Rule of 100

For items under $100, percentage discounts feel bigger ("25% off"). For items over $100, absolute amounts feel bigger ("Save $50"). Marketers use this to maximise perceived value.

// Quick Mental Math

To calculate 25% off, divide by 4. For 10%, move the decimal. For 15%, calculate 10% + half of that. For 33% off, divide by 3.
