# Usage

## The go-to command

```bash
python3 dba_pricerunner_scraper.py "YOUR SEARCH" --pricerunner --compare --verdict
```

This fetches DBA (used) + PriceRunner (new) results, prints a comparison table, and gives you a verdict:

- ✅ **BUY USED** — used is 20%+ cheaper
- 🤔 **DECENT DEAL** — used is 5–20% cheaper
- 🏷️ **BUY NEW** — used barely saves anything
- ⏳ **WAIT** — used is at or above new price

## All options

| Flag | Default | Description |
|------|---------|-------------|
| `query` | (required) | Search terms (quote multi-word) |
| `--engine` | `requests` | `requests` or `selenium` |
| `--max` | `15` | Max results to fetch |
| `--top N` | — | Show top N results |
| `--pricerunner` | off | Also fetch PriceRunner prices |
| `--compare` | off | Show side-by-side comparison |
| `--verdict` | off | Add buy/wait recommendation |
| `--format` | `text` | `text`, `markdown`, or `grid` |
| `--min-price` | — | Filter: exclude items below this price |
| `--max-price` | — | Filter: exclude items above this price |
| `--json` | off | Output raw JSON instead of tables |

## Examples

```bash
# Quick verdict (no table)
python3 dba_pricerunner_scraper.py "iphone 15" --pricerunner --verdict

# Full comparison, markdown format
python3 dba_pricerunner_scraper.py "samsung galaxy s24" --pricerunner --compare --verdict --format markdown

# Filter out cheap accessories
python3 dba_pricerunner_scraper.py "playstation 5 konsol" --pricerunner --compare --verdict --min-price 2000

# ASCII grid for terminal
python3 dba_pricerunner_scraper.py "xbox series x konsol" --pricerunner --compare --verdict --format grid

# Top 5 DBA only (no PriceRunner)
python3 dba_pricerunner_scraper.py "playstation 5" --top 5

# JSON output for scripting
python3 dba_pricerunner_scraper.py "iphone 15" --json
```

## Tips

- **Be specific with search terms.** "playstation 5 konsol" gives much better results than "playstation 5" (which picks up games, controllers, and cases).
- **Use `--min-price` to filter accessories.** E.g. `--min-price 1000` for phones, `--min-price 2000` for consoles.
- **The verdict uses the median used price**, not the cheapest. This avoids outliers (e.g. one broken console at 500 kr dragging the median down).
- **PriceRunner picks the lowest new price** across all sellers. This is your "best case" new price.

## Selenium engine

If DBA starts blocking `requests`, try:

```bash
pip install selenium webdriver-manager
python3 dba_pricerunner_scraper.py "playstation 5" --engine selenium --pricerunner --compare --verdict
```
