Scrape Competitor Book Prices for Weekly Price Comparison — Python + CSV

We are seeking freelance experts for small online used-bookstore and want to track how my prices compare to a larger competitor site. I need a Python script that scrapes their book listings so I can spot-check pricing and stock trends weekly. What I need scraped (per book): Title Price Star rating (helps me judge which titles are popular) Availability (in stock / out of stock — I want to see what sells out fast) Category Product page URL (so I can double-check listings manually if needed) Requirements: Scrape all pages on the site (~20 pages) Clean data — no duplicate rows, no broken/missing prices Output as CSV with clear headers, sortable by category and price Script should be reusable — I'll want to re-run this myself every week or two to catch price changes Deliverables: Python script (.py) Sample CSV from a first run, for my review Quick note on how to run it and any packages to install.
