  • You probably expected55% off
  • Shopify actually applies46.5% off
  • Margin at that price16.2%

These combine to a discount you can live with.

Discounts multiply, they do not add. Three discounts of 30%, 10% and 15% leave the customer paying 0.70 × 0.90 × 0.85 of the price, which is 46.5% off rather than 55%. Nothing you type here leaves your browser.
