E-Commerce Scraper Under $300

I need a reliable script that can visit one or more major e-commerce sites and pull both product details and pricing information for every URL I feed it. The final output must be a single, well-structured JSON file that I can import straight into my own system with image witouth water mark.

Key points
• Scope: product titles, full description text, specifications, images, SKU/ASIN, list price, sale price, currency, availability, and the product page link.
• Flexibility: the code should be easy for me to point at additional categories or entire sites later without rewriting the scraper.
• Tech: Python with Scrapy, BeautifulSoup, Playwright, or a similarly robust approach is fine as long as it bypasses basic blocks and respects reasonable request throttling.
• Delivery: the finished scraper, a short README explaining setup and usage, and a sample JSON export generated from a small test run.
• Budget: fixed; my ceiling is $300, so please keep the solution lean and efficient.

I will consider the job complete when I can run the script on my machine, adjust the input URLs myself, and obtain clean JSON that matches the fields above without manual cleanup.
