## How BOGO Deals Work
Buy-one-get-one promotions give a discount on the second item when you buy two. The discount on the second item can range from a small percentage to 100% (completely free).
### Formula
**Pair Cost = Full Price + Full Price x (1 - BOGO Discount / 100)**
**Effective Per Item = Pair Cost / 2**

计算示例
A store offers BOGO 50% off on items priced $12.99. You buy 1 pair.
- First item: $12.99 at full price
- Second item: $12.99 x (1 - 0.50) = $6.50
- Pair cost = $12.99 + $6.50 = $19.49
- Effective per item = $19.49 / 2 = $9.74
- Savings = $12.99 x 0.50 = $6.50
