Compare two successive discounts with a single discount, work through the sale-price arithmetic, and check how tax and rounding affect a receipt.
Two discounts usually apply one after the other, rather than being added together. Read the retailer's conditions to establish the order, what the offer covers, and whether tax or delivery charges are included.
Worked example: Apply 20% off, followed by another 10%
Input
An original price of 100, a first discount of 20%, and a second discount of 10%, before tax.
Expected result
The sale price is 72 and the saving is 28, equivalent to a 28% total reduction.
The first discount leaves 80. The second removes 10% of 80, which is 8. Adding the percentages would incorrectly give a price of 70.
Before you use the result
- Confirm whether a coupon applies to the original or already reduced price.
- Keep tax and delivery charges separate when the shop does.
- Compare rounding with the final checkout receipt.
If the result is not what you expected
The shop's price differs by a small amount.
Check whether it rounds each line or only the final total, and whether the offer excludes particular items or taxes.
