We have a chrome extension now. Try it out here
As usual this happened when I was trying to solve a problem that hampered the book search experience.
Amazon is a great place to look for books but there is no way to know what the prices are like in India so this extension lets me know what the prices are with a click of the button.
Here is a screenshot. Its simple, easy to use, very very functional and should just work wherever books are sold.
Let us know what you think.
