Hello, how are you? I'm Pedro, a pleasure to greet you, I was reading your project and I understand that you need to do a Web Scraping that allows you to extract the price data from a Web store.
Now, are you going to need to extract other data? Is it a single Web store or do you have several stores to Scratch? Do you have a Web Proxys Services to rotate the IPs? Have you worked with applications with JavaScript?
My proposal is to make a Scraping Web App in .Net that works with JavaScript Chromiun, the JavaScript Functions are more compatible with the Html of browsers and the download of data is more precise in an Access table, then with Power Query we connect the Excel and export the data.
Now, I am available to start this work as soon as possible, I have several Web Scrapers working, my latest work is the Web Scraping Amazon UK, based on JavaScript, with a filter menu, the demos of these finished projects are in my portfolio.

It goes without saying that my apps are compiled in a paid development tool and I don't use free versions and free software.
Sincerely
Pedro Requena
