Calculate savings and final price, including an optional second discount.
A 20% discount on 100 takes the price to 80. Adding a second 10% discount applies to 80, giving 72, so the effective discount is 28%, not 30%.

No. Starting at 100, the first discount gives 80 and the second gives 72, a total saving of 28%. Each percentage acts on the remaining price. Add fixed savings only in the order specified by the actual offer. Check the actual offer conditions. Check the actual offer conditions.
For equal-priced items, paying for two and receiving three reduces the price per item by one third, about 33.3%. This assumes you use all three. Check which items qualify and whether a cheaper single pack better matches the quantity you need.
Only amounts represented by the chosen mode and entered fields are included. Compare the final payable price after adding any actual delivery charges, fees or conditions outside that calculation. Keep the original price and the saving distinct so that a large advertised percentage does not obscure the amount you will pay.
