Build a simple Amazon Scraper and Calculation Program

I want a program where I can type a keyword on [login to view URL] (UK), and it gathers various data from the product listing page and fba calculator. It also does some simple calculations and inputs. I've created an example of what it should be like in an Excel file which I have attached. I created this Excel in 10 minutes with the calculations. Here is the draft plan of what need scraping: URL Title ASIN List Price List Delivery Price Total (list price + list delivery) Sales Rank New Used Collectible Open Box Sold directly by Amazon Fulfilled by Amazon Merchant Fulfilled Supplier (This is my supplier, I input myself) Cost of Item (This is my cost for item, I input myself) Cost inc VAT (Cost of Item * 1.2) Your Price (This is my Price I want to sell item for on Amazon, I input myself) Price Difference (Your Price - Price Total) Dimensions Weight FBA Fees (Copy ASIN in FBA Calculator, and scrape fees) FBA Fees inc VAT (FBA Fees * 1.2) Profit (Your Price - FBA Fees inc VAT - Cost inc VAT) Scrape the stock levels of each seller of that item, by adding to basket 999, and seeing what stock levels Amazon responds with. When I find items I want to keep. I should be able to save it to another part of the program called Saved Items. In Saved Items, I should be able to export to CSV, and Refresh/Update Data. Also it should keep a history of the data for that item when clicking refresh, so it doesn't just overwrite it. So when you open the saved item, you see a list of all the data, and the date and times it was scraped. Easy stuff.
