How it works

Saving = original price × discount percentage. Sale price = original price − saving.

Three practical tips

  • Apply stacked discounts one after another, not by adding percentages.
  • Remember that delivery can change the true saving.
  • Compare the final unit price, not just the advertised percentage.

How do two discounts combine?

Apply the second discount to the already-discounted price. A 20% discount followed by 10% is 28% off overall, not 30%.
