I need a chrome extension for Amazon trade-in books and games.
1- Extension should compare ( trade in value-selling price= z) seller price and amazon trade in price of a book or a game in one page of Amazon search results ( usually 25 items at a time).
2- show the result "z" right under the trade in value in three different colors.
Red: If the "z" is 0 ot negative
Orange: if the "z" is positive and less than 5
Green: if he is bigger than 5
