This will take you a long time to do, exactly why I am paying 2 million mp to whoever does it.
Now you must get the right price for every item!
You must count how many of each item there are and then add them up to the total for THAT item.
In the end you will have an immense amount of numbers to go through.
If you cannot find the price for an item, please DO NOT GUESS. Simply put it ASIDE and then make a PC forum with all of the items you could not find the PRICE for.
You can make a graph, chart, etc.
This will get you brownie points
