Frequently asked questions
How do I calculate a discount?
Multiply the original price by the discount percentage and divide by 100 to get the savings, then subtract that from the original price.
Are two discounts the same as adding them?
No. 20% off followed by another 10% off is 28% off in total, not 30%, because the second discount applies to the already reduced price.
