📦 Product Listings
These are fixed-price products listed by sellers. Each listing contains rich data: title, description, price, item specifics, shipping details, and seller ratings.
🔨 Auction Listings
Auction-style listings allow buyers to bid on products. The final auction price reveals what the market is willing to pay at that moment.

soup = BeautifulSoup(response.text, 'html.parser')

price = item.select_one('.s-item__price')
print(f"Product: {title.text if title else 'No Title'}, Price: {price.text if price else 'No Price'}")🤖 2. Selenium
