리뷰: 다른 사람들의 코드를 몰래몰래 봤을때 이런씩으로 처리해서 변수를 줄이는 방법도 있더군요. 시각에 따라 좋을수도 있고 안좋다고 생각할 수도 있지만 코드보다가 생각나서 넣어둘게요

```suggestion
        do {
            showInventory(products);
            BuyProducts buyProducts = buyProducts(promotions, products);
            CustomerReceipt customerReceipt = makeCustomerReceipt(products, buyProducts);
            showReceipt(customerReceipt);
        } while (inputView.continueShopping()
                      .equals(YES))
```
