Universal e-commerce scraping bot

Searching for someone with exceptional technical knowledge

I am wondering if anyone can help me find a solution to scrape all e-commerce product pages for prices. I understand how you can scrape one site, but is there a way to capture for example 90% of all e-commerce websites?

I know there are pre-made scraping bots but I am looking for a technical solution.

Thank you in advance for any help!
