I need a script that will search through different Amazon product categories and find products based on these factors:
1. Compare lowest NEW price with second lowest NEW price based on percentage difference.
2. Compare lowest USED price with second lowest USED price based on percentage difference.
3. Find products based on custom rank (popularity).
4. Find products based on custom minimum and maximum prices.
I need the script output in csv format. (ISBN or UPC code, Title, Lowest price, Second Lowest, Rank, URL of the product, condition, etc.)
I will run this script on localhost. Please, feel free to ask question and make your proposals. I have done a similar project for $100 and this is where I'm aiming my budget.
