Important assumptions

- A single percentage discount on the original price. Taxes and shipping are not included.
Financial tips
Practical guidance to act on your result.
- Two discounts in a row (for example 20% then 10%) are not the same as 30% off — apply them one after the other.
- Compare the final price, not just the percentage, when choosing between offers.
