Real websites are messy.

Some items miss fields:
- no price
- no rating
- broken tags

Your scraper must not crash.

## Bad approach
```python
price = item.select_one(".price").text  # may crash
```

## Safe approach
```python
tag = item.select_one(".price")
price = tag.text.strip() if tag else "N/A"
```

## Wrap in try-except
```python
try:
    price = item.select_one(".price").text.strip()
except AttributeError:
    price = "N/A"
```

## Flow
```mermaid
flowchart TD
  A[Find Tag] --> B{Exists?}
  B -->|Yes| C[Read Text]
  B -->|No| D[Use Default]
```

## Remember
- Missing data is normal
- Always code defensively
