About the Buy One Get One (BOGO) Discount Calculator

"Buy one, get one" promotions charge full price for the first item in each pair and a reduced price (often free or half-off) for the second, so the effective per-item discount depends on how many items you actually buy.

Formula: Total Price = Pairs × (Full Price + Discounted Price) + Leftover Items × Full Price

Buying an odd number of items means the last one doesn't qualify for the discount, which slightly lowers the effective overall discount percentage compared to buying in exact pairs.
