ad_details question

gistfile1.txt

So if we have the following line item...

line_item
  ad_distribution{:price_per_unit = 20}
  buy_item{:id = 1}
  buy_item{:id = 2,
           :price_per_unit = 40}

I think the first case is simple. Seems we should return....

```
GET /ad_details/1.json
{
  "buy_item": {
     "price_per_unit": 20,
     "ad_distribution": {
        "price_per_unit": 20
     }
   }
}
```

But for

GET /ad_details/2.json

should we return this?

```
{
  "buy_item": {
     "price_per_unit": 40,
     "ad_distribution": {
        "price_per_unit": 40
     }
   }
}
```
or this
```
{
  "buy_item": {
     "price_per_unit": 40,
     "ad_distribution": {
        "price_per_unit": 20
     }
   }
}
```
