What the result means
See the effective discount across all items in a Buy X Get Y Free offer.
Example
Buy 2 Get 1 Free means one of three equally priced items is free, an effective discount of 33.33%.
How it works
Effective discount = free items ÷ (items bought + free items) × 100
A common mistake
Dividing the free quantity by only the purchased quantity overstates the basket-wide discount. Use the total number of items received.
