"Should I buy it used?" — DBA vs PriceRunner price comparator with verdicts.

Searches DBA for used listings and PriceRunner for new prices, then gives you a side-by-side comparison with a buy / wait / buy-new recommendation.

Quick start

python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt

# The go-to command:
python3 dba_pricerunner_scraper.py "playstation 5 konsol" --pricerunner --compare --verdict

Output:

==================================================
  SHOULD I BUY IT USED? — playstation 5 konsol
==================================================
  🤔 DECENT DEAL
  Used is only 12% cheaper (~3,500 kr vs 3,995 kr new).
  Decent savings but you lose warranty & returns.
  savings: [███░░░░░░░░░░░░░░░░░░░░░░░░░░░] 12%
  new: 3,995 kr   used median: 3,500 kr   range: 198–4,500 kr
==================================================

Verdicts

Verdict	When	Meaning
✅ BUY USED	≥20% savings	Great deal, buy used
🤔 DECENT DEAL	5–20% savings	Some savings, but you lose warranty
🏷️ BUY NEW	<5% savings	Barely any savings — new is worth the premium
⏳ WAIT	Used ≥ new	Something's off, wait for better deals

Options

Flag	Description
--pricerunner	Also fetch PriceRunner (new) prices
--compare	Show side-by-side comparison table
--verdict	Add the "should I buy it used?" recommendation
--format	text (default), markdown, or grid
--top N	Show top N results
--min-price / --max-price	Filter by price (e.g. --min-price 2000)
--json	Output raw JSON
--engine selenium	Use Selenium instead of requests (for JS-heavy pages)

Examples

# Quick check: is it worth buying used?
python3 dba_pricerunner_scraper.py "iphone 15" --pricerunner --verdict

# Full comparison with markdown table (great for pasting into docs)
python3 dba_pricerunner_scraper.py "samsung galaxy s24" --pricerunner --compare --verdict --format markdown

# Filter out accessories: only look at items 2000–5000 kr
python3 dba_pricerunner_scraper.py "playstation 5 konsol" --pricerunner --compare --verdict --min-price 2000 --max-price 5000

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

# Just top 5 DBA listings (no PriceRunner)
python3 dba_pricerunner_scraper.py "playstation 5" --top 5

How it works

1. DBA — scrapes search results via requests (or Selenium). Extracts title, price, location, and URL from each <article> card.
2. PriceRunner — extracts embedded product JSON from the search results page. Gets the lowest new price for each product.
3. Verdict — compares the median used price (DBA) against the lowest new price (PriceRunner) and computes savings %.

Tip: Use specific search terms (e.g. "playstation 5 konsol" not "playstation 5") to avoid accessories and games polluting the comparison.

Requirements

• Python 3.10+
• requests, beautifulsoup4, lxml (see requirements.txt)
• Optional: selenium + webdriver-manager for the --engine selenium path
