Help me learn to write a screen scraper in C#

I need assistance shortening the learning curve to build a sample screen scraping program in c# using HTML Agility Pack and XPath to scrape data from Amazon pages, specifically the main ASIN page and sellers lists. I need to know if a given product (ASIN) is sold by Amazon and if it's sold by an FBA seller or non-FBA merchant.

I'm mostly having trouble with learning XPath or LINQ. I've considered using CSQuety but don't know jQuery and so not sure what the best path to success is. I'm an experienced developer, but just trying to come up to speed on screen scraping technology.

Looking for someone with very good english who can walk me through some specific examples.
